Hi,

Sorry if this sounds idiotic, but I'm having problems
with the MPI get operation in OpenMPI. I have test
program that calls OpenMPI's get operation, which
performs a send operation. This fails with a null
pointer exception in the opal library, after preparing
the source.

With the shared memory driver, when performing a get,
the shared memory code seems to be being passed a null
pointer. Using the TCP driver also crashes with
dereferencing a null pointer.

Anyone have any suggestions on what might be causing
the problem? I assume others are using get, so
presumably someone else will have encountered this
problem (assuming it's a quirk that's in a common
component and not in the test program).

Jonathan
