This has happened to me many times, but a simple rebuild of the Open-MPI generally fixed it.
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:
orterun.c:486: orterun: Assertion `((0xdeafbeedULL << 32) +
0xdeafbeedULL) == ((opal_object_t *) (&cmd_line))->obj_magic_id'

I have a custom installation of open-mpi, with the configure script looking like this:
--enable-debug --enable-trace --enable-memchecker --with-valgrind=/usr
The rebuild of my application was successful.
Where should I fix it? and How?
Thanks for ideas.
