<pre>Ken, please verify my bisection before spending too much time on this. It was
difficult and time consuming to reproduce. I was able to trigger the test
failure by running the test in a loop, while simultaneously running a full
piglit suite in another window. Here are the ways I invoked the two workloads:
for ((;;)) do
/tmp/build_root/m64/lib/piglit/bin/arb_gpu_shader5-emitstreamvertex_nodraw
-auto -fbo; done
and
piglit run -o -p gbm --exclude-tests timestamp-get --exclude-tests glsl-routing
--exclude-tests ext_timer_query --exclude-tests arb_timer_query --exclude-tests
spec.khr_debug.object-label_gl --exclude-tests

--exclude-tests vs-float-main-return --config

arb.compute.shader.zero-dispatch-size -c gpu /tmp/build_root/m64/test/ivbgt2
In my tests, the looping test generally failed while the first few hundred
tests in the piglit suite were executing. Occasionally, I would have to
restart the piglit suite to produce the failure. Also, the looping test failed
around test 4000 more than once.
I spent several iterations confirming that the looping test failed at the
bisected revision, and I could never make it fail on the previous revision.
This failure mode has been seen on IVBGT2 and BXT.</pre>
