Bitcoin Core 0.12.0 randomly crashes at launch on WinXP SP3 #7674

RachelPriss · 2016-03-13T11:08:51Z

Here's a debug.log fragment:

http://pastebin.com/u14vGP5z

Sometimes the app don't crash and running normally. But mostly not.

Previous version (0.11.2) works fine.

maflcko · 2016-03-13T12:05:47Z

What does the crash look like? Is the splash screen just disappearing into nowhere or does an error message pop up?

rebroad · 2016-03-13T12:27:53Z

Duplicate of #7639 (which was also on XP SP3)

RachelPriss · 2016-03-13T12:28:01Z

Always appears the standart windows message: "application will be closed, blah blah blah".

Exception Information
Code: 0xc0000005 Flags: 0x00000000
Record: 0x0000000000000000 Address: 0x0000000077c23509

Sometimes it happens during splash screen, sometimes right after the main window opens.

@coinyBit2

Could you start Bitcoin-Qt.exe (or bitcoind.exe) with gdb.exe? (You can download GDB here: http://www.equation.com/servlet/equation.cmd?fa=gdb).

Run gdb.exe bitcoin-qt.exe
Once GBD has loaded, type r.

Then wait until it crashes and pastebin the output somewhere.

And maybe you could also post your debug.log on pastebin.com.

To rule out some new/changed functionality:

Can you try with -listenonion=0
Can you try with -connect=0.0.0.0 (you won't get any connections, but does it crash?)
Can you try with -connect=<node> where <node> is an active node
Can you try with -disablewallet

rebroad · 2016-03-14T10:39:29Z

still segfaults with -disablewallet

also segfaults with -disablewallet -listenonion=0 -connect=192.168.42.69

laanwj · 2016-03-14T10:43:33Z

What about -connect=0.0.0.0?

rebroad · 2016-03-14T10:48:20Z

-connect=0.0.0.0 also segfaults.

Running with gdb gives:-

msvcrt.dll is File version: 7.0.2600.5512, md5 355edbb4d412b01f1740c17e3f50fa00

laanwj · 2016-03-14T12:31:17Z

You've also tried with -server=0? (this is the default for the UI, but you may be overriding it)
What about using bitcoind.exe instead of bitcoin-qt.exe - is this GUI specific?

It may be that the new version of mingw that is used to compile the release no longer properly supports XP. Version 0.12.x is compiled in a Ubuntu 14.04 VM instead of 12.04. Someone enterprising could try to cross-compile 0.12 on Ubuntu 12.04 and see if that improves things.

lamar8 · 2016-03-23T05:04:01Z

I compiled 0.12.0 on win 7 using mingw4.9 and qt 5.3.2. it got the same problem on Win XP(also crashed at msvcrt.dll).But after using "-listenonion=0" ,it works quite well excpet shutting down(not always).So I guess it maybe not because of cross compile in Ubuntu 14.04. Could anyone make further tests and fix it ?

laanwj · 2016-03-23T10:24:57Z

But after using "-listenonion=0" ,it works quite well excpet shutting down(not always)

Can you get a proper backtrace? ('bt' in gdb) after a crash? Previous ones have only mentioned the topmost function, while what we need is to know where the crash originates in application code.

lamar8 · 2016-03-24T13:55:51Z

I configured '--enable-debug' and compiled bitcoin-qt.exe on winXP directly, gdb with IDE(eclipse for c++),but failed to locate the additional source code,the result is :

Thread #9 0 (Suspended : Signal : SIGSEGV:Segmentation fault)

    msvcrt!___unguarded_readlc_active_add_func() at 0x77c0330c  
    msvcrt!.badioinfo() at 0x77c2f964   
    0x14f83ef2  
    msvcrt!___unguarded_readlc_active_add_func() at 0x77c0356a  
    0x165024e0  
    msvcrt!___unguarded_readlc_active_add_func() at 0x77c03c1b  
    0x0

I also tried "ollydbg", but still failed. It seems related to setlocal() function in msvcrt.dll. I don't know how to add conditional break point to stop before it crash wihie it's called too frequent

laanwj · 2016-03-24T14:12:21Z

That's unfortunate. Without knowing where the call comes from there is very little to do.

These are some pointers when googling for crashes in that function, maybe useful to someone:

https://sourceforge.net/p/mingw-w64/bugs/307/
https://stackoverflow.com/questions/17189306/how-to-trigger-mingw-to-link-msvcr100-dll-instead-of-the-msvcr-dll-within-th
https://trac.torproject.org/projects/tor/ticket/9084 ("TBB 3.0a1 crashes on startup on WinXP ")

Note that the last item, Tor Browser Bundle's gitian has a workaround to link against msvcrt100.dll instead of msvcrt.dll

  # We don't want to link against msvcrt.dll due to bug 9084.
  i686-w64-mingw32-g++ -dumpspecs > msvcr100.spec
  sed 's/msvcrt/msvcr100/' -i msvcr100.spec

And it seems we link against msvcrt.dll as well, not msvcr100:

objdump -x bitcoin-qt.exe|grep DLL
...
        DLL Name: msvcrt.dll
...

I don't have time to investigate this further, but maybe this helps someone.

I am experiencing this exact same issue on my XP machine, if there is data I can provide from my setup that would be helpful in developing a fix for this I would like to help.

Have you tried passing -listenonion=0, seems to work for at least one person #7674 (comment)

Mikestang · 2016-04-01T03:59:28Z

Tried it both in a .conf file and launched from the command line and it still crashed crashed crashed. Oh well, stuck with 0.11.2 I guess.

lamar8 · 2016-04-01T08:10:15Z

There exists a bug in msvcrt.dll, setlocal() function. It crashed at the same stack as the above google results. so it can be solved by linking msvcrt100.dll or avoid this bug like previous releases.

achow101 · 2016-04-27T18:45:56Z

@coinyBit2 Everyone who does gitian builds build all of the versions. There is no one person who just does Windows stuff or is in charge of windows builds. Since this problem is limited to XP, which has reached its EOL, no one has fixed it yet and it has not been deemed a high priority by the other developers because the issue is not seen in any other version of windows.

theuni · 2016-04-27T19:44:46Z

I don't think it's the same bug as tor's:

ubuntu@ubuntu:~/build/bitcoin/distsrc-x86_64-w64-mingw32/src/qt$ x86_64-w64-mingw32-nm -Cg bitcoin-qt.exe | grep "_s$"

laanwj · 2016-04-28T10:41:03Z

Who is compiling the Windows version? Has this been brought to this individuals attention yet?

There is no one interested in maintaining Windows XP support, you're on your own here. At some point the price of buying new hardware/software is lower than the value of the time you'll spend on getting something to work.

maflcko · 2016-04-28T11:27:40Z

You can also try a lightweight OS instead, as suggested in #7681 (comment)

tzofeolam · 2016-05-06T13:17:35Z

With information found by lamar8 and following discussion in the QT project forum it seems to be a QT library issue only.
https://forum.qt.io/topic/62162/qt-5-6-doesn-t-compatible-with-windows-xp/11
According to that discussion there is a workaround. The workaround is building QT with DirectWrite disabled (as in QT 5.5), i.e. build QT with -no-directwrite flag.

Indeed, bitcoin-qt.exe of Bitcoin Core 0.11.2 is linked with QT 5.5.0 and it works properly on Windows XP SP3 32bit.

Besides the workaround there is a real fix in the QT code. Take a look at their already fixed QTBUG-50188 bug report:
https://bugreports.qt.io/browse/QTBUG-50188
and the commit itself:
https://codereview.qt-project.org/#/c/144954/

I don't know which QT version is used in Bitcoin Core 0.12.x but updating it to the latest or making a custom QT build with -no-directwrite flag should fix the bitcoin-qt.exe crashes on Windows XP.

Please use one of the above solutions. Windows XP is not dead yet!

laanwj · 2016-05-06T13:46:00Z

@tzofeolam Interesting, thanks for figuring that out!
But unfortunately, Bitcoin Core 0.12 is also linked against Qt 5.5.0. The MinGW version did change, so it is possible that that automatically toggled -directwrite behavior.

Bumping Qt on master has to happen before the 0.13 release (and if it really fixes this issue it could be be backported to 0.12) but as the latest official release of Qt is 5.6.0, that could only make it worse in that regard.

In any case it'd be useful to experiment with that.

Mikestang · 2016-05-08T12:00:02Z

Well that is good news for us XP users, now I can only hope this gets incorporated into the next version because I am not savvy enough to employ any of those Qt fixes myself.

HenryBarton · 2016-07-17T04:12:20Z

I cannot make the 0.12.x series run on Windows XP SP3, nor will 0.11.2 run for long. The best luck I've had is with 0.10.3, but it keeps crashing at length with a message about "Expression: hashPrevBlock == view.GetBestBlock()". This is reported to be in main.cpp, line 1660.

laanwj · 2016-07-29T09:59:50Z

Closing this issue: No one with an interest in bringing back XP compatibility showed enough initiative in the time frame available. Windows XP is no longer supported as of 0.13:

Compatibility

Microsoft ended support for Windows XP on April 8th, 2014,
an OS initially released in 2001. This means that not even critical security
updates will be released anymore. Without security updates, using a bitcoin
wallet on a XP machine is irresponsible at least.

In addition to that, with 0.12.x there have been varied reports of Bitcoin Core
randomly crashing on Windows XP. It is not clear
what the source of these crashes is, but it is likely that upstream
libraries such as Qt are no longer being tested on XP.

We do not have time nor resources to provide support for an OS that is
end-of-life. From 0.13.0 on, Windows XP is no longer supported. Users are
suggested to upgrade to a newer verion of Windows, or install an alternative OS
that is supported.

No attempt is made to prevent installing or running the software on Windows XP,
you can still do so at your own risk, but do not expect it to work: do not
report issues about Windows XP to the issue tracker.
