Comment 1 Brian Paul 2012-05-01 08:13:38 UTC
It looks like the piglit test has a few bugs.  I'll post a patch to fix them.
Comment 2 Brian Paul 2012-05-01 13:15:31 UTC
Fixed w/ piglit commit a50bc91c44f21214569d2c567f803d3a92af6ab5
Comment 3 nobled 2012-05-01 13:29:35 UTC
Test failure aside, shouldn't the assert still be fixed? A buggy client shouldn't be able to cause that.
Comment 4 Brian Paul 2012-05-01 14:16:28 UTC
Yes, I already posted a Mesa patch to fix that side of it.
