PTU Error with OpenGL apps and new NVIDIA drivers

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
