Just built 1.8.3 for another round of testing with mpi4py. I'm getting
the following valgrind warning:
==4718== Conditional jump or move depends on uninitialised value(s)
==4718== at 0xD0D9F4C: component_select (osc_sm_component.c:333)

The offending code is in ompi/mca/osc/sm/osc_sm_component.c, it seems
you forgot to initialize the "blocking_fence" to a default true or
false value.
bool blocking_fence;
int flag;
if (OMPI_SUCCESS != ompi_info_get_bool(info, "blocking_fence",
&blocking_fence, &flag)) {
goto error;
}
if (blocking_fence) {
