It's worth pointing out that the test runs perfectly on SNB, so this appears to be specific to ILK (and earlier?). Also hitting this segfault. Ironlake (Core i5) here.

Fixed by applying this patchset: http://thread.gmane.org/gmane.comp.video.mesa3d.devel/30043 Thanks, David. commit 0b96b3ffa92285d281de82442743402cf374973a Author: Eric Anholt <eric@anholt.net> Date: Tue Aug 30 10:31:41 2011 -0700 intel: Restructure TexSubImage as just the 2D implementation and blit func. Fixes a segfault in piglit copyteximage where I accidentally removed the dst_bo setup in the previous cleanup.
