Charm++ parallel programming system

[Jim Edwards <jedwards AT ucar.edu>]

I've now built the AMPI_ROMIO and am trying a very simple MPI IO program.
It dies in the call to MPI_FILE_OPEN although it does manage to create a 0 length file first.

What can I do to get a more meaningful stack traceback?
