Re: [mpich-discuss] [PATCH v2] test: add attrdeleteget, MPI_Attr_get called from delete_fn

You want to call MPI_ATTR_GET on the communicator you are deleting? How is that a valid program?

The communicator shouldn't be invalidated until _after_ calling all the delete_fn, so it should still be safe to check attributes from delete_fn. The 'flag' argument is used to indicate whether the attribute is missing.
