I have a laptop with both intel haswell chip and intel HD 4400 GPU
I have VS 2012 and the 2014 beta opencl sdk installed.
I have taken the median filter sample and modified it to run my own kernel.
Using the default device "0" (CPU), everything works fine.
But, if I set device to "1", then I get an error when trying to build the opencl kernel.
i.e. when calling clBuildProgram
Yes, this is the same issue I reported in http://software.intel.com/en-us/forums/topic/508650.
The error is an access violation. So, something in this kernel makes the compiler sad.
The program works fine for two AMD GPUS that I tested on, and also Intel CPU.
You can simply run my github project to reproduce.
