Thanks muchly for tracking this down! I'm working on the fixes right now; will commit shortly.

That last value means that I'm munging the upper 32 bits of the tick
register (it's 64 bits long).  So we're not quite there yet, but
getting closer.  I should be able to get to that today.

The other problem is very odd. Since you're compiling in 32bit mode, I'd expect us to see it on our PowerPC machines, but I haven't run into that one yet. I'll try to compile without debugging and see what I can
see.

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
