--- Comment #1 from Mig <mastner at hotmail.com> ---
The same problem occurs when running the mat-mul example taken from
https://cgit.freedesktop.org/~tstellar/opencl-example
[mig at antergos-mig opencl-example]$ ./mat-mul
There are 1 platforms.
There are 1 GPU devices.
clCreateProgramWithSource() suceeded.
Speicherzugriffsfehler (Speicherabzug geschrieben)
When int is replaced with unsigned int the the program runs fine:
[mig at antergos-mig opencl-example]$ ./mat-mul
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.
clSetKernelArg() succeeded.

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