Mysterious Memset
since it's std::memset, the compiler could theoretically inline it or have a small-count path that uses vector intrinsics

It could, but for a case without a known count it doesn't really make sense to do that. (I honestly found the concern to be kind of strange for that reason, honestly.)

A memset tail call would be less code size than the loop, so it's still worth it even for cold code.
