Here's where the SegFault comes from.
For whatever reason, when working with the verbose opal_output_stream,
eventually opal_paffinity_base_open sets opal_paffinity_base_output=-1
(at paffinity_base_open.c, 62) and calls mca_base_components_open with
that value as the output_id. In turn, if output_id!=0,
mca_base_components_open calls:
=====================================
if (output_id != 0) {
opal_output_set_verbosity(output_id, verbose_level);
}
======================================
Now, opal_set_verbosity (in opal/util/output.c) unconditionally does
this:
info[output_id].ldi_verbose_level = level;
(where, for verbose, this is info[-1].ldi_verbose_level=0;)
On my system, this wipes out verbose itself.
Elsewhere in output.c, such constructs are bracketed with
if(output_id >= 0) { ... } (or if(-1 == output_id) {...}), and I suspect
that is needed here, too.
Hope this helps,
Ferris
