I haven't taken a look at the patch but I don't really know how it can be
possible to speed things up without invoking UB (I will take a look at it
today).

The obvious way to get the same performance as C is just to use a
boost::container::vector instead of std::vector. Std::vector is safer but
it is just not designed to support this use case "as efficient as possible"
(it should still be pretty fast tho).
