Hi Marc-Andre, all, As mentioned in Wesley’s email from a few days ago, Bill went through the entire standard and marked inconsistencies or possible errors. One of them is relevant for tools: https://github.com/mpi-forum/mpi-issues/issues/268 <https://github.com/mpi-forum/mpi-issues/issues/268> Marc-Andre, I assigned you to this ticket (lucky you :) ), but I think we should go though this on an upcoming tools call, as this wording can have larger consequences.
