Running MS Excel viewer, I seem to be able to crash it fairly easily when opening files. The is occurring in the apparently undocumented function EnumMRUListA, so I am not really sure what to expect here.
Unhandled exception: page fault on read access to 0x00000000 in 32-bit code (0x40a231f0).

I suppose you would have to debug it to find out why witem is null here (ie "desired" might be out of range").
