--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
You need to provide preprocessed source that exhibits that, it is not possible
to compile the snippets you've provided.  We can reduce it ourselves then.  Or
you can use multidelta and/or creduce to reduce it yourself (e.g. with a script
that g++ before PR64433 fix doesn't warn on it but g++ right after it does and
there are no errors in the source.
