Jumping in pretty late in this thread here... I see that it's failing in opal_hwloc_base_close(). That's a little worrysome.
I do see an odd path through the hwloc initialization that *could* cause an error during finalization -- but it would involve you setting an invalid value for an MCA parameter. Are you setting hwloc_base_mem_bind_failure_action or hwloc_base_mem_alloc_policy, perchance?
