I have a problem that clBuildProgram hangs. The following kernel was tested with the HelloCL sample :
__kernel void test(__local float* s1,__local float* s2,__global float4* s1_s2_result)
This happens only when compiling OpenCL 1.2 AMD-APP (923.1) for the GPU.
Compiling for the CPU goes fine.
Thanks for reporting this issue, our internal builds don't show this issue, so it most likely will be fixed in the next release.
