Control: retitle -1 beignet+mesa-opencl-icd crash if installed together
The lack of hardware isn't the trigger - having beignet-opencl-icd and mesa-opencl-icd installed at the same time is. (beignet+pocl or mesa+pocl is OK.)
Looks like some kind of "seeing the other ICD's copy of libllvm instead of their own" problem (similar to https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=768185 , and possibly appearing now because beignet just switched to the same LLVM version as mesa), but I haven't yet had time to confirm this.
