Likely an issue with your GPU and/or driver for your GPU since that test
computes formula results using your GPU.

Markus was at one point trying to gather all problematic GPU's to add to
our black list, and it's possible that your hardware needs to be on that
list.  He wrote a detector program you can run to get the detailed
information of your GPU...

I don't remember where to get that program though....  I need to dig up
the archive a bit to find out.

Use this as a workaround for now.  Markus is on vacation until
mid-October.

It's unlikely that that would affect the result of that OpenCL test, but
maybe it does.  I don't know.

That's a possibility.  The vast majority of us recommend using dbgutil
turned on, but that also adds extra baggage that you may or may not need
(plus extra build time and disk space).  So, if you are interested in
doing just casual coding, then using a non-dbgutil build may be an
option.
