The binaries were built using the following libraries:
giflib-4.1.4-1
gnutls-2.10.1
jpeg-6b-4
libXpm-3.5.8
libpng-1.4.3-1
tiff-3.8.2-1

Which GCC version? I have seen numerous crashes with the last windows
build which is compiled with gcc 4.6.1.

I used gcc 4.6.1 (tdmmingw32).

What OS? Do you have any backtraces from the crashes?

I have been using the last build on a regular basis on Windows 7 without
problems.

Someone reported crashes on XP with gcc 4.6.1 compiling with -O2, but
the binaries are compiled without optimizations.

Microsoft Windows [version 6.1.7601]

Did the OS save the crash reports somewhere (sorry I have been using
windows OS for only 3 weeks and I don't have gdb running)? Otherwise I
can try and get a crash in a day or two.

Each application crash is recorded in the system log that you can view
using the "Event Viewer" (right-click on "My Computer", select
"Manage", then expand the "Event Viewer" widget and click on
"Application").

> Otherwise I can try and get a crash in a day or two.

Thanks, but there's no need to do that in this case, as the cause of
these crashes is known, see

  http://lists.gnu.org/archive/html/emacs-devel/2011-10/msg00871.html

This is now in etc/PROBLEMS.

However, I would advise to install GDB anyway, for when you need it
the next time.

The textual description is much better, because it includes
descriptions of the <Data> field, instead of relying on the schema.
There's a "copy to clipboard" button on the "event properties" dialog,
which you can use to paste the textual description into the mail.

Yes, that's the same crash that I cited.

Yes, I used the copy button but then deleted the parts containing
Chinese chars. A full version looks like this:

Leo said that this happens with the last weekly build I provided. It was
compiled _without_ optimizations. The original report claimed to compile
with `-O2'. 

Just to make sure, is specifying `--no-opt' enough to disable
optimizations when configuring or do I have to specify `-O0'
explicitely?

If this turns out to be a problem with 4.6.1 in general, I will switch
back to an older version. Or should I use `-fno-omit-frame-pointer'?

I didn't realize the above crash was with your binaries.  If it was,
it's probably a different problem.  Leo, if you have a way of
reproducing this, please run under GDB and produce a backtrace, or
better yet, show the recipe (and file a bug report).

Specifying --no-opt is enough.

With --no-opt, -fno-omit-frame-pointer should have no effect, because
this optimization is turned on by -O1.

I looked around in the tdm bug tracker but I couldn't find any issues
related to optimization or `-fno-omit-frame-pointer' reported for 4.6.1
so far.

This may not be related to gcc version since I have also seen it in an
Emacs built with gcc 3.4.

All crashes happened during completion (such as in C-h f or C-h v).

It seems to have something to do this setting in my .emacs:
(setq completion-styles '(basic initials substring partial-completion))

The problem is not specific to tdm, it's a general problem of any GCC
port to Windows that uses the Microsoft runtime.  I posted here the
URL that describes the bug in more detail.  It only happens with
`-fomit-frame-pointer', i.e. with any optimization at or above -O1 (if
I understand correctly the GCC manual and if the manual is accurate).

If you cannot easily reproduce this, just run Emacs under GDB at all
times.  The debugger stays out of your way as long as Emacs doesn't
crash.
