Dear Open MPI developers, This bug report just came in against the new Open MPI 1.3 release which we built the same way as 1.2.*.
Christophe, Sorry about that. And yes, it should be a drop-in replacement. You can revert back to 1.2.8 from testing for now. If you have a small self-contained C++ example, it would help debugging.
