<pre>Software versions:
4.3.0-rc3
OpenGL version string: 3.0 Mesa 11.1.0-devel (git-a29d922)
GPU hardware:
OpenGL renderer string: Mesa DRI Intel(R) Haswell Desktop
00:02.0 VGA compatible controller [0300]: Intel Corporation Xeon E3-1200
v3/4th Gen Core Processor Integrated Graphics Controller [8086:0412] (rev 06)
CPU hardware:
x86_64
Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz
Khronos CTS version:
git@29e4891ef6
command:
./glcts --deqp-case=ES31-CTS.gtf.GL31Tests.shader_helper.shader_helper
Environment:
Mesa built with: --enable-debug
export MESA_GLES_VERSION_OVERRIDE=3.1
export MESA_EXTENSION_OVERRIDE=GL_ARB_compute_shader
-----------------------------------------------------
With debug build the ES31-CTS.gtf.GL31Tests.shader_helper.shader_helper asserts
with:
glcts: nir/nir.c:1569: nir_intrinsic_from_system_value: Assertion `!"system
value does not directly correspond to intrinsic"' failed.
Aborted (core dumped)
On a build without debug the test segfaults.
This issue is blocking OpenGL ES 3.1 conformance testing.
The regression was bisected to the following commit:
commit 20748318c5b870fc27f699637041e67a67321f5f
