--- Comment #5 from Eero Tamminen <eero.t.tamminen at intel.com> ---
Reason why Mesa compiler finishes compilation with Martin's setup, is that his
versions of demos have different shaders.

Only my versions output this when Mesa compiles compute shaders:
Unsupported form of variable indexing in CS; falling back to very inefficient
code generation

(My UE4 demos are from June 2014, Martin's from October 2014.)

While this may be a bug in the shaders, Mesa still shouldn't just freeze
forever in compilation. -> Leaving this still open, but it could be considered
lower priority.
