Dear OpenMPI developers, I think the source code modification titled "Ensure that we don't try to call orte_show_help() before orte_init() succeeds." is buggy (see [1] at lines 755-763). There is no difference between the if and the else path of the code, i.e. checking orte_setup/rte_setup makes no sense. You will find the erroneous code below the 'error' label in ompi/runtime/ompi_mpi_init.c in SVN trunk, too.
Kind regards, René [1] https://github.com/open-mpi/ompi-svn-mirror/commit/b200ea0e1554d40ed4948f9823fc6dd7b0cc3ba6#diff-3673b21a7f42dc0665ea4470b3171df1
