<pre>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
<a href="https://en.wikipedia.org/wiki/List_of_Intel_graphics_processing_units">https://en.wikipedia.org/wiki/List_of_Intel_graphics_processing_units</a>), 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?</pre>
