OK, a few more tests. I was using PGI 10.4 as the compiler.
I have now tried OpenMPI 1.4.3 with PGI 10.8 and Intel 11.1. I get the
same results in each case, mpirun seg faults. (I really did not expect
that to change anything).
I tried OpenMPI 1.5. Under PGI, I could not get it to compile. With
Intel 11.1, it compiles. When I try to run a simple test, mpirun just
seems to hang and I never see anything start on the nodes. I would
rather stick with 1.4.x for now since that is what we are running on our
other production cluster. I will leave this for a later day.
I grabbed the 1.4.3 version from this page.

When you say this bug is fixed in recent 1.4.x releases, should I try
one from here?

For grins, I compiled the OpenMPI 1.4.1 tree. This what Myricom
supplied with the MX roll. Same result. I can still run with their
compiled version of mpirun, even when I compile with the other build
trees and compilers. I just do not know what options they compiled with.
Any insight would be appreciated.
