There isn't enough information there to be able to help. At the very least you'll need a stack trace plus information about your OpenCL driver, some code, your compilation options and so on... but realistically it's not possible to debug a problem like this without actually sitting at your computer.

I don't see how that can compile given that pLocal is never defined. I also don't see how it can be computing a dot product, given that it outputs an array rather than a single value

Are you using the Intel OpenCL SDK on an AMD CPU? In my experience, this combination doesn't work, while the reverse (AMD APP with Intel CPU) works.
