What exactly was the error here? The Travis regressions are passing CUDA 4.2.

No error message was output, but the simulator will just be stalled without any progress.

Sorry I let this die for so long...
I am really wondering what the use-case you observed the hang in is. We regress against CUDA 4.2 (which is obviously < 6) and the code does not hang. It seems very odd to me that this code should be CUDA-version specific.

My configuration:
OS: ubuntu 14.04.1
gcc:4.6.4
cuda:4.2
simulator config: SM2_GTX480
use-case: all workloads in ispass2009
Fix the bug that the ptx parser will be blocked when CUDART_VERSION < 6000.
