MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD with errorcode 65.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes. You may or may not see output from other processes, depending on exactly when Open MPI kills them.

Sorry, I had a typo with the double colon, it should be a single colon
