            Bug ID: 100067
           Summary: [OpenCL] const int in argument list crashes build
           Product: Mesa
           Version: 17.0
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org

When running the program:

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

it crashes. valgrind output is:

==3618==  If you believe this happened as a result of a stack
==3618==  overflow in your program's main thread (unlikely but

==3618==  main thread stack using the --main-stacksize= flag.
==3618==  The main thread stack size used in this run was 8388608.

It does not so when the int arguments in the OpenCL kernel are changed
to unsigned int.
