Commen= t # 1 on bug 10006= 7 from Mig 
The same problem occurs when running the mat-mul example taken=
 from

https://c=
git.freedesktop.org/~tstellar/opencl-example

[mig@antergos-mig opencl-example]$ ./mat-mul
There are 1 platforms.
There are 1 GPU devices.
clCreateProgramWithSource() suceeded.

When int is replaced with unsigned int the the program runs fine:

[mig@antergos-mig opencl-example]$ ./mat-mul=20
There are 1 platforms.
There are 1 GPU devices.
clCreateProgramWithSource() suceeded.
clBuildProgram() suceeded.
clCreateKernel() suceeded.
clSetKernelArg() succeeded.
clSetKernelArg() succeeded.
clSetKernelArg() succeeded.
clSetKernelArg() succeeded.

clSetKernelArg() succeeded.
clSetKernelArg() succeeded.
50 94 178=20
60 120 220

Maybe it is related to the fact that the platform reports as 64bit adresssp=
ace:
(clinfo reports incorrectly the "Global memory size" beeing 7GB w=
hereas it
shpuld report 2GB)
