Recursive Gaussian blur fail on Intel HD 4000 with lastest driver version

Recursive Gaussian blur fail on Intel HD 4000 with lastest driver version

Hi Intel Tech support and all

I download the opencl recursive blur sample from Nvidia at http://developer.download.nvidia.com/compute/DevZone/OpenCL/Projects/oclRecursiveGaussian.zip. it run ok on AMD graphic card and Nvidia graphic card. When running the sample on Intel CPU, the result is as expected, but when running the kernel on Intel HD 4000 GPU, it fail. I run into this problem when update the graphic driver to the lastest version. The sample binary run as expected with the driver before version 15.31.3.3071. 

Does anybody know anything about this problem? Will next driver version fix this driver issue?
