Hello,
In the case of single process the MPI_Ireduce_scatter_block is
segfaulting with v1.9a1r26786.
But in other cases (commsize >= 2) processes hang in
MPI_Ireduce_scatter_block. The NBC_Progress hangs during rounds processing.
The following example illustrates this problem:
$ cat ireduc
(cross-post to 'users' and 'devel' mailing lists)
Dear Open MPI developer,
a long time ago, I reported about an error in Open MPI:
http://www.open-mpi.org/community/lists/users/2012/02/18565.php
Well, in the 1.6 the behaviour has changed: the test case don't hang forever and
block an InfiniBand
Hello -
Thank you for the bug report. This has been fixed in the trunk.

After some digging Terry and I discovered the problem with r26626. To perform
an rdma transaction pmls used to explicitly promote the seg_addr from
prepare_src/dst to 64-bits before sending it over the wire. The other end would
then (inconsistently) use the lval to perform the get/put. Segments
I wouln't consider sourced variables being overritten by the sourcing platform
file a problem. I can update the platform file documentation to make sure this
behavior is clear. Can you point me at the right faq page?
