Parent: 963311b mesa/main: fix version/extension checks in _mesa_ClampColor
Follows: 13.0-branchpoint (2236)
main/fboject: return if it is color_attachment on get_attachment

G33 is not in the developer pool for CI tests (machines too rare and too slow), so Alejandro could not have seen this before pushing.
FYI, G33 uses i915_dri.so, not i965_dri.so. Pretty much any hardware which uses that older driver would probably reproduce this.
My bisection was incorrect. The tests regressed at the previous commit:

mesa/main: fix version/extension checks in _mesa_ClampColor
That test doesn't call glClampColor (and if it did, that would be incorrect). So that's odd.
Does i915 use some of the meta code? That might be calling _mesa_ClampColor without proper checking.

Of all the internal callers of _mesa_ClampColor, there's one that isn't properly guarded, and that piglit test should hit it -- so the attached patch should fix this, but please test and confirm on i915. Thanks!
Nicolai's patch fixes the test for me.
