Subject: [OMPI users] Strange Segfault in mpirun: orterun.c:486

Hello All, This has happened to me many times, but a simple rebuild of the Open-MPI generally fixed it. I had a perfectly working (and tested) MPI application till a few days ago. Since then, there has been some upgrades on my Linux OS (basically, the ones which the system picks up automatically). Now, I rebuild and rerun the same application, I get this: mpirun: orterun.c:486: orterun: Assertion `((0xdeafbeedULL << 32) + 0xdeafbeedULL) == ((opal_object_t *) (&cmd_line))->obj_magic_id' failed.

Where should I fix it? and How? Thanks for ideas. Best Devendra
