        <pre>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 <a href="https://bugs.freedesktop.org/attachment.cgi?id=92645">https://bugs.freedesktop.org/attachment.cgi?id=92645</a> on
top of Mesa 10.1 git branch and it worked, no more SIGFPE.

Stacktrace of SIGFPE without the patch:
