Dear Wesley,

https://github.com/mpi-forum/mpi-issues/files/3704357/153_neighbor_mpi-3_bug_2019-10-08.pdf
includes the full solution, but I have not yet build a pull request.
No time for that up to now.
I hope that I can do it during or after the meeting.

The most important is that all vendors/owners of MPI libraries fix this 
bug in their MPI implementation, therwise MPI_NEIGHBOR_ALLTOALL/V/W
is not usable in cyclic Cartesian applications.
(May be that they all already fixed it. Upto now, I've the 
fixed notice only from OpenMPI and HPE MPT.)

Therefore the reading slot is important.

Best regards
Rolf
