[mpiwg-tools] question about MPI_T_EVENT_GET_INFO

[Marc-André Hermanns]

Dear Ken,

yes, I think you are right in your assessment.

I created a ticket

https://github.com/mpi-forum/mpi-issues/issues/438

and an accompanying PR

https://github.com/mpi-forum/mpi-standard/pull/518

and we should get this out as quickly as possible as an Erratum to 4.0

Cheers,
Marc-Andre
