I found another case where taking a backtrace causes a SEGV.

This time the error occurs when the unwinder attempts to deal

with a frame that saves some of the xmm registers.  The code

in question is in the openmp (shared) library distributed

with the intel compiler.



The component at fault here is libgcc_s.so.  The patch of

2011-05-24 fixed the SEGV, and returned a correct backtrace.
