On my end, I am working on a resync of AdaCore's "head" version,
which would include this change as well. My testing shows that
it revealed some issues; I haven't had a chance to look into them yet
(next on my list today, hopefully), but this is making me think
there might be bona fide issues. Getting the location where things
are happening is pretty nice :).
