--- Comment #7 from Török Edwin <edwin+mesa at etorok.net> ---
This also affects FlightGear 3.0. If you set View->Rendering Options->Quality
to 5 then it crashes with a SIGFPE.

I tested the patch from https://bugs.freedesktop.org/attachment.cgi?id=92645 on
top of Mesa 10.1 git branch and it worked, no more SIGFPE.

Stacktrace of SIGFPE without the patch:
