this is not a bulletproof one, but it does fix your problem.
in this case, MPI_Ineighbor_alltoallw is invoked with sendbuf ==
recvbuf, and internally,

Giles,
Thanks for the small bug fix. It helped clear up that test case but I'm
again running into another segmentation fault on a more complicated problem.
I've attached another 'working' example. This time I am using the
MPI_Ineighbor_alltoallw on a triangular topology; node 0 communicates

Thanks for the report and the test case,
this is a bug and i pushed a commit to master.
for the time being, you can download a patch for v1.10 at

I'm trying to use the neighborhood collective communication capabilities
(MPI_Ineighbor_x) of MPI coupled with the distributed graph constructor
(MPI_Dist_graph_create_adjacent) but I'm encountering a segmentation fault
on a test case.
I have attached a 'working' example where I create a MP
