segmentation fault inside clBuildProgram (bug demo attached)

I am experiencing a segmentation fault inside the call to clBuildProgram when using the Intel platform and Intel Xenon CPU.   This is for a relatively complex kernel / OpenCL program.  Simple kernels build fine.  I am not having any problem building the same source code on the Apple or NVIDIA platforms.

I am attaching a bug demonstration program with as simple kernel.  Please private message or email me for the offending kernel source code file.

g++ -o build_bug_demo opencl_program_build.cpp bugDemoSupport.cpp -I$OPENCL_INC_DIR -L$OPENCL_LIB_DIR -lOpenCL

# Here is what I see for the offending program source:
./build_bug_demo -p 2
Selected CL_PLATFORM_NAME: Intel(R) OpenCL
CL_DEVICE_NAME: Intel(R) Xeon(R) CPU           X5650  @ 2.67GHz
CL_DRIVER_VERSION: 1.2.0.92
