[OMPI devel] Segmentation fault in MPI_Get in the Vader/sm module

[Max Schrötter via devel]

Hi everyone,

I recently opened an issue on github, before reading on the OpenMPI site
that I should have posted my problem here, sorry.

I get a segmentation fault when using one sided communication on a
new communicator created by MPI_Comm_split.

All the details are on github : https://github.com/open-mpi/ompi/issues/8434#

I also might have found a possible solution.

It would be great if someone could have a look at the issue and try to
reproduce it or tell me if my test code is wrong.

Thanks,
Max
