bench_cg.py fails with NVRTC Error

Running bench_cg. py from the examples, gives me this error:

@umar456 I thought this was fixed on 3.6 ?

[umar456]

Yeah, thats what I thought. I haven't looked at this yet. Will get to it later today.

Hi Guys,

I have the same issue in some of my own codes. How do I at least get a more meaningful error message, such that I know that the code to be JITed it too big??

thanks,
Tom
