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.
