bug#5769: 23.1; Emacs crash on Windows 7 right after startup

[Tamas Czinege]

On launching Emacs 23.1.0 on Windows 7 32bit (using the official build), Emacs
crashes right after displaying the Emacs window. Using
a debugger, I got the following information:

Unhandled exception at 0x0109cf0d in emacs.exe: 0xC0000005: Access
violation writing location 0x0242fffc.

Stack trace:

Note that the problem can be temporarily worked around by adding
the following line to my .emacs:

(setq inhibit-splash-screen t)

or just invoking Emacs with --no-splash. That allows emacs
starting up, but it still crashes in a minute or so, apparently
completely randomly. Note that this still happens even
when invoked with -q --no-site-file.
I'm not sure if this is a bug or there's something wrong
with my installation but it offers no apparent clue if that's
the case.

Do you have Cygwin directories in your PATH? It could be a result of
incompatible image libraries.

bug#5769: 23.1; Emacs crash on Windows 7 right after startup

[Tamas Czinege]

I don't have Cygwin installed on that box, and have no Cygwin
directories in the PATH. The debugger gives the following list of
loaded modules that are not part of Windows:

emacs.exe	C:\emacs\bin\emacs.exe	23, 1, 0, 0										
libXpm.dll	C:\emacs\bin\libXpm.dll											

and both of them seems to me loaded from the right location. It might
be very well some sort of image library conflict as disabling the
splash image hints it. I suppose making a custom build with debug
symbols compiled in and stepping in with a debugger would help. I'll
let you know what I find.

Sorry, I don't think anything can be done with report as it stands.
If it still happens with the current version of Emacs (currently 24.2),
please make a new report and hopefully we do better next time.
