Re: [OMPI devel] Commit r16105

[George Bosilca]

The setup of a communicators include as a last stage, a collective communication. As a result, some of the nodes can exit the collective before the others and therefore can start sending messages using this communicator [while some of the other nodes are still waiting for the collective completion]. This will lead to a situation where a node receive a message for a communicator that they are building up.
