--- Comment #2 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- > You are using Mac OSX and an invalid recursive I/O, see pr30617. I did not look at the end of the report. So apparently recursive I/O hangs also on Linux debian and MPI(?). Without the MPI stuff the code hangs on darwin, but not on gcc version 4.6.3 20120306 (Red Hat 4.6.3-2).
