Ok, I think we have this resolved in trunk and the fix will go into 1.7.4. The
check for MPI_IN_PLACE was wrong in the mpif-h bindings. The fix was tested
with your reproducer. Both MPI_SCATTER

I have an MPI code that was developed using MPICH1 and OpenMPI before the MPI2
standards became commonplace (before MPI_IN_PLACE was an option).
So, my code has many examples of GATHERV, AGATHERV and SCATTERV, where I pass
the same array in as the SEND_BUF and the RECV_BUF, and this has worked f
