Cuda-gdb gets stuck on ++

On seemingly random occassions a kernel under cuda-gdb gets stuck. It just never finishes.
I ctrl+c to see what happens. It’s always stuck on a line that does ++.
I’ve tried moving out a++ from b[a++] to a see that it’s actually the incrementation that fails, and it appears to be so.

Is this a common or otherwise known PEBKAC, or a bug in cuda-gdb?

Should I file a bug report?

I’ve had no luck using cuda-gdb whatsoever, it always freezes when using “next” or “step”. AFAIK it’s only officially supported for Red Hat on linux, but I hear the 2.3 SDK has cuda-gdb support for all major linux distros.

N.

Yeah, I know only RHEL is “really” supported, but I can get it to work, mostly.

I bump this in the hope of getting any comment from nvidia :)
Should I expect the debugger not to work reasonably well under anything else than red hat?
