Created attachment 54998 --> https://bugs.freedesktop.org/attachment.cgi?id=54998 terminal output and backtrace

When running Khronos Webgl test suite there is an occasional crash and gpu hang. This is not 100% reproducible with one test, sometimes it finishes whole test run OK, sometimes it hangs really fast. Running glsl functions subtests few time is a row reproduces it here always.
