@remexre thanks for the report. Can you please try by passing --disable-generations to configure and report back?

It looks like I get the same result, including a very similar backtrace.

remexre commented Nov 21, 2019

Doing disas on the stack trace, looks like it crashes on pxor (%esp), %xmm0 when %esp = 0xbfffdb9c -- does Racket not keep the stack 16-byte aligned? Or is the real fault with https://gcc.gnu.org/bugzilla/show_bug.cgi?id=40838 ?

OK, I will try to reproduce.

@remexre I can build this under emulation inside a debian chroot with gcc 7.4.
Logs are here:
https://gitlab.com/racket/racket/-/jobs/356919983/raw

A few more questions:

  • Are you building this natively on a 32 bit machine?
  • Can you show me you /proc/cpuinfo?
  • I am assuming you did something before make cstartup. Can you post full build logs pls?

It's a native 32-bit machine, yeah.

There was no error on the build above though, was there?

Oh, grr, looks like it didn't capture stderr; it segfaulted as before.

ok - then, no problem. I have what I need. Thanks.

I assume you are untarring the 7.5 tarball, cd src, and then ./configure --disable-generations && make ?

I'm also passing --prefix=$HOME/.custom-racket/ to configure, but otherwise yes.

Thanks. I will need some more time to investigate. No problem is revealed in emulation. Maybe I can get my hands on a 32bit machine.

I suspect reproducing this relies on the options your glibc was compiled with -- it looks like a stack alignment thing to me.

@remexre Have you compiled your glibc with any special options? This should be pretty standard accross distros unless you have done it yourself.

@remexre Although the stack is meant to be 16-byte aligned, it looks like there's one place where alignment is only enabled for Mac OS. Can you try changing line 420 of "src/racket/src/lightning/i386/core.h" from

# ifdef _CALL_DARWIN

to

# if 1

and see whether that helps?

I believe CFLAGS should be -fno-builtin-strlen -ggdb -fomit-frame-pointer -O2 -march=native -pipe; I'm on Gentoo, so it was compiled on my CPU with a distro-provided build script.

The change to lightning seems to have worked, though racket3m and racketcgc both have a multisecond time-to-repl; do you see a regression on your machine?

@remexre If you run raco setup racket first, do subsequent repl startups get faster?

Or perhaps just completing make and then running make install.

That cut it down from ~10sec to ~3

Depending on which one you did, a full raco setup may reduce the time further.

Also, what's the time for racket -l racket/base?

After the raco setup, 0.700 total.

That's a time that seems within the realm of possibility for a slow machine (I get 0.277).

Okay, this works to my satisfaction; should I close this, or is there some code change that should be landed (eg a configure option for alignment)

Re-assigning to @mflatt

Still don't understand why this was not causing problems in other x86 configurations. Any ideas?

No clue, but it'd be plausible to me that Ubuntu, Debian, Fedora, etc. compile their libc with unaligned stacks to prevent issues with software unaware of the ABI change.

@remexre you're on the money here.
From arch build pkgs: https://git.archlinux.org/svntogit/packages.git/tree/trunk/PKGBUILD?h=packages/glibc

  export CC="gcc -m32 -mstackrealign"
  export CXX="g++ -m32 -mstackrealign"

This is slightly unfortunate to say the least. @mflatt will close this one when he sees fit.
@remexre thank you for your time and patience with this one.

Yes, c611f12 was meant to close the issue, but I forgot to mention the issue number in the commit. I'll close this issue now.
