There is a "bug" in cmdproxy.exe which should never happen, but does
anyway. In make_absolute, there is the following code:
strncpy(dir, path, p - path);
dir[p - path] = '\0';
If p-path > sizeof(dir), a buffer overrun occurs.
I came across this problem because I accidentally used ':' as a
separator when constructing the PATH variable in Emacs.
Thanks,
Sohail

Thanks, this is now fixed for Emacs 24.4 (revision 117021 on the
emacs-24 branch).
