Thanks for the quick reply.    I'd still argue that this is a bug in
parallel hdf5.  What I mean is a nice error message saying that this is a
known limitation of PHDF5 because it depends on ROMIO and MPI and 32 bit
signed integers and a link to the  FAQ would be much much better than the
stack trace that the current code generates.    The current behavior makes
it look it is a bug in PHDF5 when it is not.

Thanks,
