--- Comment #6 from Sergei Trofimovich <slyfox at gcc dot gnu.org> ---
gcc internals doc says that binfo should be attached to every class/struct
(RECORD). I'm not sure if this case qualifies. Maybe?
Why this crash happens mechanically? I skimmed through commit 65870e75616ee43
("cp: add support for per-location warning groups.") and found a few places
where warning suppression was removed.
Returning the one around ptrmem prevents the crash from happening:
