Subject: Re: [OMPI users] SIGSEV when running OMPI Java binding

Greetings, and thanks for trying out our Java bindings.

Can you provide some more details? E.g., is there a particular program you're running that incurs these problems? Or is there even a particular MPI function that you're using that results in this segv (e.g., perhaps we have a specific bug somewhere)?

Can you reduce the segv to a small example that we can reproduce (and therefore fix)?
