--- Comment #5 from Mark Janes mark.a.janes@intel.com --- I was able to reproduce this bug using the old versions of piglit and mesa

piglit: 1f39e07d44f7d78557d69c505168afb8eab913c6 mesa: c2a0600

After updating piglit to the latest revision, the test skips. This seems to be the correct behavior, since g33 does not support occlusion query.

Based on this information, it seems safe to conclude that this bug is the result of running an obsolete/buggy version of piglit, and does not indicate a regression in mesa.
