Function operator new

src/fl/stl/shared_ptr.h:121–124

Aligned operator new/delete: when T has alignment > default new alignment (e.g. FL_ALIGNAS(64)), plain `new` won't honour it on pre-C++17 compilers. GCC emits -Waligned-new in that case. These overrides route through fl::aligned_alloc / fl::aligned_free so the block is always properly aligned.

    // GCC emits -Waligned-new in that case.  These overrides route through
    // fl::aligned_alloc / fl::aligned_free so the block is always properly aligned.
    static void* operator new(fl::size_t size) FL_NOEXCEPT {
        constexpr fl::size_t align = control_block_alignment<T>::value;
        return fl::aligned_alloc(align, size);
    }
    static void operator delete(void* ptr) {
        fl::aligned_free(ptr);
    }
