Hi Folks,

Does anyone in the WG recall what our thoughts were concerning
the case when MPI encounters an error in an MPI function
not associated with a particular communicator, file, window, or
(now) session?

I’m concerned about this sentence in 8.3:

When using the MPI calls that are not related to any objects are considered to be attached to the communicator


Looking at the old power point slide deck, this problem is mentioned, but not
