Bill/Kees/Justin should review that patch upstream but bumping the required version for __counted_by to clang-24 (or maybe 23.1.x if it can land in release/23.x) kind of sucks :/ but if this is a big enough footgun that we don't want to continuously workaround, I guess we have no choice. -- Cheers, Nathan
