Hack to prevent crash

Well, I made a little progress. Turns out that this bug is present at least as
far back as Wine 1.0. And commenting this line out of DispCallFunc in
oleaut32/typelib.c prevents the crash:

call_method( func, argspos - 1, args + 1, &stack_offset );

Of course, the Logic Analyzer doesn't actually do anything without that line,
but it at least doesn't go to the black screen of death.

I saw that call_method is implemented as 33 lines of inline assembly. Could
there be a bug somewhere in these 33 lines?
