I believe this one has already been fixed and is in the nightly (1.7.4rc2) - for now, you can just set "--bind-to none" on the cmd line to get past it

Testing with Solaris 10 on SPARC, I was expecting to encounter the bus error reported previously by Siegman Gross.  Instead I see the following hwloc-related abort:

Open MPI tried to bind a new process, but something went wrong.  The
process was killed without launching the target application.  Your job
will now abort.

  Error message:     hwloc indicates cpu binding cannot be enforced

2 total processes failed to start

I am assuming I just need some magic pixie dust to disable cpu binding.
I'd appreciate some corresponding instructions.

However, if this is NOT an expected/desired/known behavior please let me know what I can/should do to help determine the root cause.
