I tried to free COMM_SELF, and it seems to call the error handler attached to COMM_WORLD. Is this intended? Should'nt OMPI use the error handler to COMM_SELF?
As reference, I tried this with MPICH2, and of course the call fails, but using the error handler in COMM_SELF. Again, this is a new corner case AFAIK not taked into account in the standard.
