Hi Nathan,
surely, OpenMPI was compiled with the Valgrind support:
%/opt/mpi/openmpi-1.8.4.dbg/bin/ompi_info | grep -i memchecker
MCA memchecker: valgrind (MCA v2.0, API v2.0, Component v1.8.4)
The following configure options were used:
--enable-mem-debug --enable-debug --enable-memch
Have you turned on valgrind support in Open MPI. That is required to
quite these bogus warnings.

Hi,
Our parallel applications behaves strange when it is compiled with Openmpi
v1.8.4 on both Linux and Mac OS X platforms. The Valgrind reports memory
problems in OpenMPI rather than in our code:
=4440== Invalid read of size 1
==4440==at 0xCAD6D37: ompi_osc_rdma_callback (osc_rdma_data_m
