Hello Ralph,
Here is the command that I use to run my application:
/home/Morpheus/CustomInstalledPrograms/OpenMPI-1.4.2/bin/mpirun -np 2 -v --timestamp-output --tag-output --d kdbg ./MPIDerivedDataTypes
where MPIDerivedDataTypes is the sample application.
Best,
Devendra

That is indeed rather strange. The failure occurs at a rather trivial point in the code, well before anything useful can happen. What does your cmd line look like?
