Smaller testcase in C


The program hits a segv on windows at the the same spot as Wine, so this isn't
related to an ole call failing or a bad free.

It seems that Windows wraps calls to a timer proc that go through the default
windows procedure (but not user handling of WM_TIMER) in an exception handler
that ignores segv's. I can't find that documented anywhere, but the attached
test program proves it (tested on XP).

I'll try sending a patch to wrap the call in a __TRY{} handler next week.
