Ah, you are using OpenMPI on a 64bit machine.

The problem might either be an openmpi issue (which I doubt) or more likely 64bit related.

Still there are some annoying and supspicious error messages and warnings, namely:

libibverbs: Fatal: couldn't read uverbs ABI version.
--------------------------------------------------------------------------
[0,0,0]: OpenIB on host uldum was unable to find any HCAs.
Another transport will be used instead, although this may result in
lower performance.
--------------------------------------------------------------------------
--------------------------------------------------------------------------
[0,0,0]: uDAPL on host uldum was unable to find any NICs.
Another transport will be used instead, although this may result in
lower performance.
--------------------------------------------------------------------------
===================================================

Does starting your program with "mpirun pamgtest" change the picture?

There is another sequential test called amgtest, would you be so kind to try if it crashes, too.
