I'm using /opt/intel/opencl-1.2-3.0.56860/lib64/libintelocl.so
All the programs I have function using the Nvidia OpenCL driver for CUDA 5.0
All my programs seg-fault with the Intel device. I'm running .Red Hat Enterprise Linux Server release 6.2 (Santiago)
On a dual-socket 4 core Intel(R) Xeon(R) CPU E5620 @ 2.40GH
Heres a picture of the stack:
