That error number (-30) means "CL_INVALID_VALUE". It's on the one hand a very generic error that can theoretically occur at almost any OpenCL command. On the other hand I have not seen this error being reported in the past with darktable.
Best guess is a driver issue as you both seem to use the same 340.76 version. I'll give that version a try later. If you have a chance to downgrade to a version like 340.58 this might give an indication as well. That earlier version does run here without issues.
