I think I've solved my problem:
in the previous code the arguments of the MPI_Comm_spawn_multiple
where filled only by the "root" process not by all the process in
the group. Now all the ranks have all that information and the spawn
is done correctly.
But I read on http://www.mpi-forum.org/docs/mpi21-report/node203.htm
that those information are significant only at root.
You are exactly right -- this is a legitimate bug! I've fixed our
development trunk in https://svn.open-mpi.org/trac/ompi/timeline and
have filed a CMR to get this fix into 1.3.4.
Thanks for the report!
