Description

Created attachment 133182 Blender crash dump

On Ubuntu 17.04 with a AMD Radeon R9 380 (Tonga Pro chipset), daily Mesa from Padoka PPA (version 1:17.3git170731230100.df61a050z~padoka0), both Blender 2.78 and 2.79 daily build (09eac0159db) crash when the OpenCL kernel is compiled for GPU rendering.

Steps to reproduce:

1. Start Blender with CYCLES_OPENCL_SPLIT_KERNEL_TEST=1 ./blender due to missing detection of OpenCL support (probably due to #101594).
2. Under Render settings, switch Device to GPU Compute and assert this setting is actually used.
3. Start a render and assert the OpenCL kernel is compiled.

Actual behavior:

• Blender crashes during kernel compilation (crash dump of 2.79 build is attached).

Expected behavior:

• Blender renders with OpenCL.

Addtional info:

• clinfo and glxinfo output is attached as well.
