Comment 13 Jerry James 2020-02-10 21:19:21 UTC 
It looks like the tuning code tried to count the number of CUDA/OpenCL devices on the system.  When the count came out zero, it threw an exception, CLCudaAPIError.  Nothing catches that exception, so you got the default C++ abort due to an uncaught exception.

I have asked upstream to please catch that exception.  In the meantime, all I can suggest is that you don't try to tune 0 devices. :-)  Thanks for the report.
