Forgot to mention that I'm running Ubuntu 10.04. Also, the cal sample apps run fine, with no segfaults at all. Cheers!
Sorry chrisgregg i missed this one.
Can you answer a few questions:
Can you provide your CPU,GPU & Catalyst?
Do you face the segmentation fault while running samples for GPU and CPU both.
Are You able to run the CAL Samples?
Is your problem fixed. We are still waiting for a test case
