Defined in header <locale>
protected: ~messages();
Détruit une facette std::messages. Ce destructeur est protégée et virtuelle (en raison de destructeur classe de base être virtuel). Un objet de std::messages type, comme la plupart des aspects, ne peut être détruit lorsque l'objet std::locale dernière qui implémente cette facette est hors de portée ou si une classe définie par l'utilisateur est dérivé de std::messages et met en œuvre un destructeur public .
Original:
Destructs a std::messages facet. This destructor is protected and virtual (due to classe de base destructor being virtual). An object of type std::messages, like most facets, can only be destroyed when the last std::locale object that implements this facet goes out of scope or if a user-defined class is derived from std::messages and implements a public destructor.

    // std::messages<wchar_t> c;  // compile error: protected destructor
