Subject: OpenCL runtime errors

Lukas, magnum -

Somehow four of the OpenCL formats don't work for me on this system
where I previously had a mix of Nvidia and AMD stuff, which I've now
temporarily tried to clean up to just Nvidia.  The errors are different.

The rest of the OpenCL formats work fine - specifically, all of
Samuele's fast hashes and magnum's new RAR with OpenCL pass the tests.
So my setup is not 100% broken. ;-)  (Also, all CUDA stuff works.)

The segfault for cryptsha512-opencl occurs with a delay of 10 seconds or
so.  All or some of this is probably something I'll need to deal with on
my end (such as by reinstalling), yet I thought it might be helpful to
have this recorded.
