It's not entirely clear that this means that it is a bug in Open MPI
-- there's not really enough information here to say where the problem
is. All that is clear is that a seg fault is happening somewhere in
LAPACK.
FWIW, I don't see MPI in the call stack of the segv at all. This
doesn't definitively mean that MPI is not involved, but it does
suggest that the bug is elsewhere. You might want to run this under a
debugger or examine the generated corefiles to see exactly what the
problem was.

All,
I had a similar problem as James described in an earlier message:
http://www.open-mpi.org/community/lists/users/2008/07/6204.php
While he was able to recompile openmpi to solve the problem, I had
no luck with my RedHat Enterprise 5 system.
Here are two other threads with similar issues regarding openmpi on
Ubuntu and OSX which were solved: https://bugs.launchpad.net/ubuntu/+source/binutils/+bug/234837

Now...
Here is my story:
I had Quantum Espresso (QE) running without problem using openmpi.
However, when I tried to recompile QE with a recompiled fftw-2.1.5,
it compiled without any error. But when I ran QE, it gave me the
error below:
*** Process received signal ***

From what I read from the above links, it seems to be a bug in
openmpi.
Please share your thoughts on this, thank you!
