I have added this patch to openmpi 1.5.3. Previously, every mpicc
would crash, now mpicc is fine. However, mpirun still crashes like
this:
% mpirun -np 8 cpi-openmpi

--------------------------------------------------------------------------
mpirun noticed that process rank 6 with PID 13662 on node pax8e.ifh.de
exited on signal 11 (Segmentation fault).

I am using RHEL6.1 and the affected Intel 12.1 compiler.
