--- Comment #1 from Howard Hinnant <hhinnant at apple.com> ---
Yeah, don't use this:

protected:
    _LIBCPP_ALWAYS_INLINE
    basic_ostream() {}  // extension, intentially does not initialize

This is essentially an implementation detail of the basic_iostream constructor
and avoids doubly initializing the underlying basic_ios.

You should instead call this constructor:

basic_ostream(basic_streambuf<char_type,traits>* sb);

with an appropriate streambuf pointer.
