The new reduce_scatter_block test is segfaulting with v1.7 but not with

comm->c_coll.coll_reduce_scatter_block()
it's NULL. (So is comm->c_coll.coll_reduce_scatter_block_module.)
Is there some work on the trunk that should be CMRed to v1.7?
Yes. All in good time :).
Does this also apply to ibcast? These failures complicate wading
through MTT results, so we each have our own idea what "in good time"
means. :^( Anyhow, test ibm/collective/ibcast_f08 is segfaulting on
v1.7. If I look at nbc_ibcast.c:ompi_coll_libnbc_ibcast(), it looks
like "handle" is used before it's initialized. The trunk doesn't have
this problem. Anyway, here's one plea for cleaning up v1.7.
