Subject: Re: [OMPI users] MPI_ERR_IN_STATUS from MPI_Bcast?

Nifty! Yes, I agree that that's a poor error message. It's probably (unfortunately) being propagated up from the underlying point-to-point system, where an ERR_IN_STATUS would actually make sense.

I'll file a ticket about this. Thanks for the heads up.
