To do so we would = need to break abi again. It seems to be a limited issue as you need a non-optimized build. The only impacted member is the _M_next() which is a simple static_cast, I'm very surprised that it's not always inlined even if non-optimized. Apart perhaps documenting it I cannot think of anything to do.=
