El constructor por defecto es protegida: sólo las clases derivadas pueden std::ios_base construir. El estado interno está definido después de la construcción. La clase derivada debe llamar basic_ios::init() para completar la inicialización antes de usarlo por primera vez o antes del destructor, de lo contrario el comportamiento no está definido .
Original:
The default constructor is protected: only derived classes may construct std::ios_base. The internal state is undefined after the construction. The derived class must call basic_ios::init() to complete initialization before first use or before destructor, otherwise the behavior is undefined.

[editar] Notas

Lo mismo se aplica a los constructores de la clase siguiente en la jerarquía de E / S, std::basic_ios. Además las clases derivadas de (std::istream y std::ostream) siempre se construyen con un objeto streambuffer hormigón y basic_ios::init() llamada, posiblemente más de una vez, para completar la inicialización de su base virtual .
Original:
The same applies to the constructors of the next class in the I/O hierarchy, std::basic_ios. Further-derived classes (std::istream and std::ostream) are always constructed with a concrete streambuffer object and call basic_ios::init(), possibly more than once, to complete initialization of their virtual base.
