I don't have any problem with what we've in this PR for MPI_Gatherv, but what I would like to see is MPI_Gatherv wrapper for how it's used in pFUnit repository.
i.e. I see that in pFUnit it's use case is something like:
call Mpi_GatherV( &
& sendBuffer, numEntries, MPI_CHARACTER, &
& recvBuffer, counts, displacements, MPI_CHARACTER, &
& this%root, this%mpiCommunicator, ier)
