rev115543: On Windows7, emacs -Q crashes with a SIGSEGV when attempting
to visit a file. I have run emacs in gdb and here is the back trace:

One clarification, if emacs is invoked with the filename to visit on the
command line:
$ emacs somefile.txt
Then there is no crash. But if emacs is invoked without any command line
arguments:
$ emacs -Q
and then C-x C-f is used to visit a file, emacs crashes before the dired
buffer is displayed.

I have compiled emacs with CFLAGS="-O0 -g" and tested again. With these
flags, the crash doesn't happen. So this might either be a timing
related issue or an uninitialized variable type of problem.
Please let me know what kind of other tests I can run to narrow this down...
