basic_ios has a bunch of rather interesting initialization requirements according to the standard (related to why it has an init function at all), and the constructor isn't really supposed to initialize in some cases.

I think to preserve that, and the original flow of the code, you should add an Init function to the both fill types in place of the constructor and call it here.
