BUG: SIGSEGV Segmentation fault in clWaitForEventsHI

Hi,

I believe I have found a bug in the OpenCL driver library for linux. I get a segmentation fault (sometimes) when calling wait for events across several GPU's and driver versions.

I have made a small example program that triggers the bug. I have attached it (amdbug.cpp). Reversing the order of the two events (line 71 & 72) makes the program run without problem.

Hope this helps tracking down the bug.

I look forward to hearing from you.

Best regards

Troels Blum
