I am able to reproduce this on BDW, so I'm going to assume it occurs on all Intel GPUs. Since this occurs only on Mesa master, the version should be git (not 11.0... where the test passes).
Bisected to: fba4823a916b63f279955dbe6d98b6efc666f53e is the first bad commit commit fba4823a916b63f279955dbe6d98b6efc666f53e Author: Kenneth Graunke <kenneth@whitecape.org> Date: Fri Aug 28 01:43:23 2015 -0700 i965: Don't do legacy userclipping in non-compatibility contexts. According to the GLSL 1.50 specification, page 76: "The shader must also set all values in gl_ClipDistance that have been enabled via the OpenGL API, or results are undefined." With this patch, we only enable clip distance writes when the shader actually writes them. We no longer force a value to be written when clip planes are enabled in the API. This could mean the first varying slot would be used as clip distances - I believe it should be the safe kind of undefined behavior. Empirically, it doesn't seem to cause a problem.

Patch sent to the mesa-dev mailing list: http://lists.freedesktop.org/archives/mesa-dev/2015-October/098469.html Olivier: Can you please test this patch. Thanks.
The bug is not reproduced with the patch, the result of the test is pass.
Fixed by the following commit. This commit should also get into 11.0.5. commit 7b3684877c97a23c62c95609fd20c845dc33f44c Author: Ian Romanick <ian.d.romanick@intel.com> Date: Tue Oct 27 14:50:14 2015 -0700 i965: Do legacy userclipping in OpenGL ES 1.x contexts. Commit fba4823a disabled user clipping for everything except compatibility profile. Core profile and OpenGL ES 2.0+ have all removed the classic, OpenGL 1.0 user clip planes. ES 1.x, however, still has them.
