Yeah, unfortunately with results like that (works on Nvidia and AMD, fails on Intel), it seems pretty sure that it's an Intel OpenCL driver bug :( I assume you're running the most recent Intel driver version -- if so, you're pretty much out of luck. As you said, you might just have to warn the user that it won't work on Intel, or only enable OpenCL if you're on Nvidia or AMD.
