LOL, we have a bug in the kernel and you try to "fix" this in MESA?

If I recall correctly there's a check whether the OS can handle
masked/unmasked sse exceptions. It causes trouble even in Windows if
the app using Mesa has it's own exception handlers installed IIRC. SSE
works just fine. Just disable the (useless) _mesa_check_os_sse_suppor
stuff (ReactOS supports this, no need to do the check) or find a way
to stop the exception from propagating.

It causes some kernel mode exception. The code deliberately throws an
SSE exception to see if the OS supports them. The trap handler considers
this as a k-mode exception and bug checks.
See http://jira.reactos.org/browse/CORE-6776

What exactly does it cause? And shouldn't we rather fix that,
instead of
disabling optimizations? mesa is already slow enough.
