Emacs23 occasionally crashes (segmentation fault) just after starting
it. Here this was the first time with Emacs 23.3 (Debian's package).
All crashes of Emacs 22 and 23 I got occurred immediately after
starting it, and most of them (if not all) occurred either on an
XML file or when Emacs was started via svn to write a log message.
Here's a backtrace:

In case this matters, I use fvwm with ActivePlacement.

All of your reported crashes seem to be in a call to `getenv', which
is a library function, called by GTK routines deep in the GTK code.
It is hard to imagine that they could be Emacs problems, especially
since you see them since Emacs 22.
In any case, backtraces from optimized programs are unreliable.
Please try rebuilding Emacs with -O0 in CFLAGS, and if you can
reproduce these crashes in the unoptimized build, follow up here with
the backtrace.

Could you please show the backtrace until it reaches Emacs code?
Thanks.

Unless Emacs has corrupted the memory earlier. Unfortunately,
one cannot use valgrind on Emacs.

I've rebuilt Emacs with -ggdb -O0. I now need to wait for another
crash, hoping that the -O0 won't make the bug disappear.

It was meaningless: I got nothing until __libc_start_main.
With the rebuild (I also installed the -dbg versions of the
libraries, when available in Debian), I should have more
information for the next crash...

That's definitely a possibility. However, it is strange that only you
see these problems for several versions. If Emacs corrupts memory so
early into the session, many other users would be affected.

No, because other users have a different configuration. I'm quite
sure that the configuration matters as I got such crashes on
different machines (where I use the same config).
By configuration, I mean the .emacs, but also the graphical
environment (e.g. the window manager, fvwm in my case, and its
configuration). That wouldn't be the first time an application
is affected by the window manager. See
https://bugzilla.mozilla.org/show_bug.cgi?id=551678
for instance, where I could reproduce a bug only with manual/active
placement.

This rebuilt GNU Emacs 23.3.1 crashed for the first time.
Core was generated by `emacs mpfrtests.data'.
Program terminated with signal 11, Segmentation fault.
I've attached the full backtrace.

It appears this is due to Fcall_process not restoring environ before
after UNBLOCK_INPUT. This is too late in your case.
The patch below against trunk, ought to fix it with minimal
intervention. But I think a better fix would be to abandon the use of
vfork and just use fork (which should be almost as fast), as the work
in the child process after vfork is undefined behavior as far as I can
understand.

Better yet, we can use posix_spawn, falling back to gnulib's
implementation of posix_spawn in terms of fork or vfork. Unfortunately,
posix_spawn has no way of telling the child to setsid, so the best we
could do would be setpgrp. I have patches to use posix_spawn in the
call_process case, but not the async case.
I'm not entirely sure how much of a difference avoiding setsid makes. In
the meantime, retaining support for vfork would be nice, because on some
platforms, like Cygwin, fork is still very slow.

Yes, looking into the problem more deeply I realize that the patch is
wrong. In fact it only substitutes one race condition for a more
severe one.
posix_spawn may be the right thing but I don't know how broadly available it is.
Another possibility would be using vfork+execle, as far as I can see
it is standardized, has been available for quite some time and it
won't make problems with setsid. The use of execvp is likely just due
to the age of these parts.

Any news on this bug? Debian's GNU Emacs 24.3.1 is still affected.
I get even more crashes (up to around 100% of the time under some
conditions) with gtk+ 3.13.9:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=762438
but I'm not sure whether this is exactly the same bug (the crashes
just occur at the same place).
I haven't tried the patch yet.

Same question here.

The failure scenario described in <https://bugs.debian.org/699325#17> was fixed
in Emacs trunk bzr 111064; see Bug#13054 <http://bugs.gnu.org/13054>. This fix
is in the next Emacs release, and the fix should be easily backportable to older
Emacs releases.

I audited the Emacs trunk source code for getenv-related races that have
undefined behavior and could have the reported symptoms. I found some other
races and installed a fix for them as Emacs trunk bzr 118095. I expect this
patch to be harder to backport to older Emacs versions, and less urgent as the
races appear to be less likely.
Since we have fixes installed in the trunk I'll take the liberty of closing the
Emacs bug report. Please let us know if the bug occurs even with the fixes; if
that happens I plan to reopen the bug report and look into it further.

Hmm... if it's in trunk it's not going to be in 24.4, so not in the next
release, right?

Trunk from 2 years ago. Actually the cited change was in 24.3.
(This is the point when I again ask people to include the "Version:" tag
when they close a bug.)
But since https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=699325
claims to be also present in 24.3, that change cannot have fixed it.

Oh hey, it's in the subject of this mail too.

Whoops, no it wasn't. But it will be in 24.4.
I got confused by the fact that it appears in src/ChangeLog.12 dated
before the "Version 24.3 released" statement.
I did say that merging those ChangeLog "version foo released" statements
between branches would confuse people in just this way; I still think
that.
