> We don't need 16-byte alignment on MSVC, we only need 8 because alignof(max_align_t) is 8 on that platform, and malloc is required to provide memory that's aligned to that boundary.

If allignment provided by malloc is sufficient, there is no need in runtime alignment. and `alignas(alignof(long double))` should be OK.
