           Summary: [OpenCL] const int in argument list crashes build
           Product: Mesa
           Version: 17.0
          Hardware: x86-64 (AMD64)
                OS: Linux (All)

When running the program:

https://github.com/CNugteren/myGEMM/blob/master/extra/minimal.cpp

it crashes. valgrind output is:
