Could not start the application (14) if len($TMPDIR) >= 30

Hi,

This is probably an internal bug in cuda-memcheck – I guess the buffer for the temp filename is too short.

If I have $TMPDIR set with len($TMPDIR) >= 30, I get the output:

========= CUDA-MEMCHECK
========= Could not start the application (14)
========= No CUDA-MEMCHECK results found

It works if I set $TMPDIR to a shorter value.

This is with cuda-memcheck from CUDA 6.5.

Some more details here on StackOverflow.

If you are a registered developer, try using the CUDA 7.0 Release Candidate and see if the issue is present there as well.
