Short description of error
Well, It just does not start. Latest (Mon May 8 05:02:20 2017 ) daily build terminal output:

blender-softwaregl works fine.
Blender-tpaw (snap packge) works as well, but if I remember correctly it also uses softwaregl.
Blender starts up and works perfectly well if I use AMDGPU-PRO drivers, but I cannot use this all the time (due to other GPU-related tasks not working with it).
If I use laptop with integrated Intel GPU it also works perfectly with i915 from Mesa 17.0.2.

There seems to be a conflict in LLVM version used by various components (the backtrace goes from libLLVM-3.6.so.1 to libLLVM-4.0.so.1), This is never a good idea to mix various LLVM version in the same namespace. In Blender we work around that by marking all LLVM/Boost related symbols as private and not visible by other process.

My guess here is that there is some OpenCL component which is linked against different LLVM version that your Mesa. Some steps to try and see how that affects on the issue:

Check whether clinfo command also crashes
Uninstall all Beginet OpenCL packages
Run Blender in a following way CYCLES_OPENCL_TEST=NONE ./blender

Thank you!

I purged all Beginet OpenCL packages and Blender started up normaly.
