El constructor por defecto es trivial: no inicialización tiene lugar distinto cero de inicialización de objetos estáticos y local de subprocesos. std::atomic_init se puede utilizar para completar la inicialización .

Original:

The default constructor is trivial: no initialization takes place other than cero de inicialización of static and thread-local objects. std::atomic_init may be used to complete initialization.
