that is not a "cache flush cpu exception" but a SIMD/SSE exception.
And looking at the asm code it seems this divide-by-zero fault is generated on
Google says that this is probably part of a runtime SSE detection routine to
detect if the OS supports SIMD exceptions.

The problem is wine doesn't properly recognizes and responds to this exception.
Needs some testing first what exactly windows does here.

I'll try to look into this if no one beats me to it.
