Hi repeatedly getting a segfault in umath. Its an internal test tool that performs some analysis on PCM voice streams using scipy. I don't really know how to debug the issue but here is the information I collected from the last segfault. I can provide more info if necessary, just need to be pointed to some instructions.

Cheers,
Hank
