Subject: Re: [OMPI devel] [Open MPI] #2043: sm BTL hang with GCC 4.4.x
From: Eugene Loh (Eugene.Loh_at_[hidden])

Both. It originally meant we need to get the fix out ASAP. Follow-up
e-mail (Louis sent privately to me, I responded just now to the users
list to publish/archive the info) suggests that our fixes don't fix his
problem. So, the fixes are insufficient, or he's encountering a
different problem.
