Turns out there are edge cases where an MTL's isend
method may end up marking a send request complete prior
to returning to the CM code. The would end up causing
problems in the bsend path since the ompi_request_complete
would end up getting invoked a second time on this request.
This ended up causing segfaults, etc. in ompi_request_complete .
