Mellanox - It looks like someone fixed the segfault when calling start_pes() when the CM PML is in use. However, I'm not sure that a clean abort is much better. With the proc tags code (in both the trunk and v1.7), there's no reason that you can't initialize both the btls and mtls. This may require some additional coding, but I think it should be doable. I'm happy to help with advice / discuss implementation issues, but not supporting OpenSHMEM when the CM PML is in use is unacceptable and is, in my mind, a blocker for v1.7.
