   Here we go again. It is not CRASHING; it has detected an error conditioning and trying to appropriately and cleanly terminate. The reason it needs to use MPI_Abort() is that often detecting error conditions is not a uniformly collective thing. 

    Printing a suitable error message and ending is not crashing. But with all the badly formatted “error messages” printed by MPICH I can not control at the end it looks like it is crashing.
