Thanks Pavel

I compiled 520b53364c73c75c4ff400d639dad13630f0e6fc with WITH_MEM_JEMALLOC=OFF and run it with fglrx 15.302 but cycles failed and blender crashed. Here's the --debug-cycles output:

Try remove ~/.config/blender, uninstall mesa-opencl and build 9e566b06e3e10e2a6514ee09354abfe90c538284 with this config:

The lastest working version on fglrx is 520b53364c73c75c4ff400d639dad13630f0e6fc
But only if it compliled with "WITH_MEM_JEMALLOC OFF" option

If I install libjemalloc-dev and recompile blender, then cycles engine does not render over gpu.
If I build blender without libjemalloc-dev, then opencl rendering work fine.

I'm just build blender from src (git://git.blender.org/blender.git) and now cycles gpu render work for me.
What information can help you to fix this bug?

However I feel that there must be something you can do since I have a scenario where it is working, and that's using 2.78a with the workaround from T50269 applied and using the driver 15.201. Here's the --debug-cycles output of that:

Considering that the same build of Blender works on a different driver, I'm pretty sure that AMDGPU is to blame here, not Blender.

Under fglrx the holders of such cards get another error: https://developer.blender.org/T49465

Out of host memory means your computer ran out of memory, theres no bug here.

Uh, fglrx was discontinued..

Yes, but it's only way to use opencl 1.2 on r9 280x. For several years amdgpu-pro is not support GCN 1.0 cards.
