Crash(s) in Emacs from CVS - W2K

[Dhruva Krishnamurthy]

Hi,
 I am using Emacs on W2K built with the latest CVS source using MINGW32
 tools. I have found a two scenerios which teads to a crash.

Scenerio 1:
when I do a "M-x highlight-compare-with-file" from a buffer containing
a C++ file. The "ediff" window comes up and then the crash.

Bug Recipe:
1. Launch emacs (with --no-init-file)
2. Visit a CPP file (contents of file: "// Dummy file")
3. M-x highlight-compare-with-file & select any file.
4. Crash

Scenerio 2:
 I launch emacs with "emacs -nw --no-init-file" in the W2K command
 shell, I get a crash immediately.

 The second scenerio (emacs -nw) was working a week back (approx) as I
 remember having used it. I plan to build with MSVC++ 6.0 and try
 debugging.
