that looks like the problem I had with my intel build of openmpi. I
could solve it by upgrading the Intel Compiler version to 126.96.36.1993:
% icc -v
icc version 12.1.2 (gcc version 4.4.5 compatibility)
% icc -V
Intel(R) C Intel(R) 64 Compiler XE for applications running on
Intel(R) 64, Version 12.1 Build 20111128

After a rebuild of the openmpi runtime, the crashes went away. I was
using openmpi 1.5.3, but you could still have the same problem.
