Eric, can you reproduce?
I can reproduce this.
The test apparently calls abort() if it can't find any black pixels, i.e. nothing was drawn. (This is rather stupid; it should fail, not abort...) Exposing GL 2.0 caused Glean to start testing a GL_POINT_SPRITE_COORD_ORIGIN of GL_LOWER_LEFT, which fails. Previously, it only tested GL_UPPER_LEFT, which appears to still work. So the newly exposed functionality is broken, but the old functionality hasn't regressed as far as I can tell.
I'm in favor of fixing the test to not abort and taking the bug off the blocker list.
The segfault was a problem with the test case, and it is fixed by piglit commit ddff74c. Point sprites don't work on Pineview, and this is already tracked by bug #23053.
Verified.Fixed.
