--- Comment #5 from cqwrteur <unlvsur at live dot com> --- It's evident that there's a flaw in the standard, making it impossible to allocate uninitialized memory for freestanding environments. That's precisely why I reported it as a potential issue for future proposals. Unfortunately, some individuals, including yourself, mistook my intent for trolling. The truth is, we can't have features that rely on compiler magic to be implemented by users; this necessitates reporting it as a Defect Report (DR) to WG21. While std::addressof still had a workaround via __builtin_addressof, you're currently left without such an alternative. Perhaps it would be beneficial for the standard to introduce specialized functions like constexpr_allocate_at and constexpr_deallocate_at, similar to construct_at. These functions could offer a constexpr-compatible means of allocating memory without involving allocators or operator new. see this issue: https://github.com/microsoft/STL/issues/4002
