Subject: [OMPI devel] Intercomm Merge

Is there a plan to fix the problem with MPI_Intercomm_merge with 1.7.3 as stated in this ticket? We are really in need of this at the moment. Any hints?

We face the following problem.

Parents (x and y) spawn child (z). (all of them execute on separate nodes)
x is the root.
x,y and z do an MPI_Intercomm_merge.
x and z are able to communicate properly.
But y and z are not able to communicate after the merge.

Is this bug in high priority for the next release?
