Open Radar

 
Summary: 
When using Xcode5-DP to compile an OpenCL .cl file into bytecode for later calling it using the built GCD stubs, an exception is thrown causing the app to crash.

I think openclc is generating bad bytecode somehow.

Steps to Reproduce:
Run the attached project, or try and call a simple OpenCL function that does something as simple as:
__kernel void doPrintf() {
    printf("Hello\n");
}

Via the GCD interface:
dispatch_queue_t queue = gcl_create_dispatch_queue(CL_DEVICE_TYPE_CPU, NULL);

dispatch_sync(queue, ^{
    cl_ndrange range = {1, {0}, {2}, {0}};
    doPrintf_kernel(&range);
});


Expected Results:
I'd expect the bytecode to load and run

Actual Results:
An exception is thrown:

Regression:
This does not occur with Xcode 4.6.

Notes:
This also affects my application "Acorn".
