Hi Rebecca,

Just tested the patch (on top of the debian-beignet-git-repo) with llvm 7. 
The workaround works for me, in a sense everything is better than a segfault! 

So the opencv_perf_dnn test now completes (although there are still some other
opencl related errors in part with build-options, but those could very well
be opencv bugs).

Thanks for the help and patch!
