PTU Error with OpenGL apps and new NVIDIA drivers
Running on Redhat 5 64-bit linux machines (tried on several different ones) with NVIDIA driver 185.18.14 or later, if I try to profile (vtssrun) any OpenGL app using ptu 3.2, I receive the following errors:

2714602317306492 : 2a95f18680 : CRITICAL : 'dlsym' for '_Exit' error Bad file descriptoropen log '(null)': Bad address
write log: Bad file descriptor
2714602317342532 : 2a95f18680 : CRITICAL : 'dlsym' for '_exit' faild. Error Bad file descriptoropen log '(null)': Bad address
write log: Bad file descriptor

If I roll back to 173.x.x drivers (specifically 173.14.12) the profiling works as expected

Thank you very much for your feedback.
We do not declare support of the statistical callgraph technologies currently used in PTU.
It means we will not be able to help you with this issue resolving.
However, we will keep you posted when statistical callgraph based on new supported technologies becomes public.
