debug bitcoind, the gdb notice "unhandled dyld version" msg.

[lovecodelc]

i work on mac os, i compile source code with "./configure --enable-debug", when use gdb attach bitcoind's pid , it shows:
"warning: unhandled dyld version (15)
0x00007fffe026ac8a in ?? ()"

i break at 0x00007fffe026ac8a, it actually break "main" function?
and it show "?? ()" ??
but i file bitcoind symbol tables, it does not work.

do you have such problems when develop program on mac os?
thank you.

This looks like a local problem on your system, or a general issue with MacOSX debugging. Do you have success debugging any other locally compiled code?

GDB itself seems to be somewhat broken on the latest version of OS X (10.11), which seems to be Apple's fault. Try googling "During startup program terminated with signal SIG113, Real-time event 113", or for issues with "GDB OS X Sierra".

If I run GDB with bitcoin-qt

Reading symbols from src/qt/bitcoin-qt...

done.
(gdb) run
Starting program: bitcoin-qt 
During startup program terminated with signal SIG113, Real-time event 113.

Trying to attach to an already running bitcoin-qt process I see the same error as you.

This Apple StackExchange answer suggests that disabling SIP is required, but I haven't tested it yet.

Thank you.
I have write a program with boost lib and debug it successfull. this problem bothers me several days.

@fanquake
thank you.
i think there is something wrong with third-party library(maybe gdb version is low?) when debug bitcoin program, i write and debug another test programs successful.

Closing this for similar reasons as #8812
