Ralph and Jeff, I've been digging and find the problem is wider than just the one library and has manifestations specific to FreeBSD, NetBSD and Solaris. I am adding new info to the ticket as I unearth it.
Additionally, it appears this existed in 1.8, 1.8.1 and in the 1.7 series as well. So, would suggest this NOT be a blocker for a 1.8.2 release. Of course I am willing to provide testing if you still want to push for a quick resolution. -Paul On Mon, Aug 4, 2014 at 1:27 PM, Ralph Castain <r...@open-mpi.org> wrote: > Okay, I filed a blocker on this for 1.8.2 and assigned it to Jeff.
