Bug #54279
Updated by Casey Bodley about 2 years ago
NoInitAllocator inherits from std::allocator<__u32>. c++20 removed a lot of deprecated things from std::allocator (see https://en.cppreference.com/w/cpp/memory/allocator). we should probably be specializing std::allocator_traits for NoInitAllocator now, rather than inheriting from std::allocator
built with gcc 11.2.1, with c++20 enabled in cmake:
