I would start by posting in the forums as you did (below). I'm not aware 
of an official bug tracker either.

Excellent. Hopefully sounds like the issue may already have been fixed.

Yes, I would have posted to the same place.

Normally elrepo only releases the long term branch for Enterprise Linux, 
on the assumption EL users will welcome the implied stability over more 
frequent and potentially buggy releases.

In this case I had built the current short lived release as a user 
requested it for compatibility with the latest CUDA. However, as it is a 
short term branch release, it will stay in the testing repository 
indefinitely and will not be promoted to the main repository. Once it's 
been superseded by a subsequent long term branch release I will likely 
just delete it from the testing repo. That said, it should be fine to 
use (at your own risk).
