What does the switch -localonly do? The mpiexec I use has an option to
disable all communicators in case you really just want to run a regular
program on a bunch of nodes. I doubt an MPI program would be able to
init in this situation.

Does this happen with the hello world program? Can you run the program
in a debugger? If not just stick std::cout << "Got here!" << std::endl
in various places to see what's going on.
