command:
./glcts --deqp-case=ES31-CTS.compute_shader.*
Environment:

Mesa built with: --enable-debug
export MESA_GLES_VERSION_OVERRIDE=3.1
export MESA_EXTENSION_OVERRIDE=GL_ARB_compute_shader
-----------------------------
Segfault when running all GLES 3.1 compute shader tests. It is not the same
test that segfaults on consecutive runs. However, the most prominent test to
segfault is:
ES31-CTS.compute_shader.work-group-size
It is also possible to segfault when only running:
ES31-CTS.compute_shader.work-group-size
The issue is bisected to:
