Disasm of one affected function

So, I managed to find one affected function: gdi32/text.c:EnumFontFamiliesExW
Attaching disassembly of EnumFontFamiliesExW.

Lines of note:
> b8 02 00 00 00       	mov    eax,0x2
> c4 e2 7b f7 95 64 c7 	shrx   edx,DWORD PTR [ebp-0x389c],eax
> ff ff

I also edited the crash handler to output the data of the illegal instruction,
it changes randomly, here's 3 samples:
> c4 e2 0f 8b bd 44
> c4 e2 0f 8b cf 44 
> c4 e2 0f 8b e1 44

Seems like enigma screws up that shrx instruction.
