[Bug 92749] seg fault in glTexImage2D

--- Comment #4 from Ian Romanick <idr at freedesktop.org> ---
I tried the trace with a very, very old version of apitrace and current master.
 I was unable to reproduce the segfault with current Mesa master on Broadwell
on either version.  If I'm cross referencing CPUs to GPUs correctly (using
https://en.wikipedia.org/wiki/List_of_Intel_graphics_processing_units), we
should have about the same GPU.

I do get:

After this there a bunch more instances of the Multi-LOD fast clear performance
warning.  Through the whole thing I just get a black window.

Can you provide a backtrace from the segfault?
