--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> --- > allocator::max_size() is worse than useless Fixed that for you. https://cplusplus.github.io/LWG/lwg-active.html#3044 https://cplusplus.github.io/LWG/lwg-closed.html#197 For PR 78448 I recently changed std::vector<T, A>::max_size() so it won't return anything greater than PTRDIFF_MAX, even if the allocator stupidly says it can handle more than that. But the standard explicitly requires the allocator to be stupid, so I'm not sure what more libstdc++ can do here.
