--- Comment #3 from Martin Sebor <msebor at gcc dot gnu.org> ---
Eric, thanks for putting so much effort into helping triage and make progress
on these bugs!  FWIW, I think the diagnostic maintainers are mainly focused on
the design and implementation of diagnostic infrastructure, not so much on
deficiencies in its client code, so CC'ing them on bugs like this is probably
not going to help move them along.  (I'll let David and/or Dodji correct me if
I'm wrong here.)
