--- Comment #3 from Jeffrey A. Law <law at redhat dot com> ---
I see what's going on here.  I'm a bit concerned there's a deeper issue.  Some
planned gcc-9 work would take care of this, but I was hoping to avoid those
changes in the gcc-8 cycle.  Investigating the deeper concerns and alternate
(less intrusive) fixes.
