Well, what do you think we can to to deal with this bug?

And what can we do from the CUDA packaging side except for a new
NEWS/README.Debian section?

I plan to point out these in the new NEWS/README.Debian section:
(1) Try to compile the whole CUDA application with clang-3.8
(2) Append the PIE/PIC flags to compiler arguments, reference: [1]
