9567	De-serialization of enable_shared_from_this through base class pointer fails	Tim Regan	Robert Ramey	"Given the following class structure:
   Base is a simple class.
   Derived inherits from Base.
   Derived also inherits from boost::enable_shared_from_this<Derived>.
   Base and Derived implement boost::serialization.

When deserializing an instance of Derived into a vector of boost::shared_ptr<Derived>:
   Base and Derived members are reconstructed correctly.
   Derived::shared_from_this() works as expected.

But when deserializing an instance of Derived into a vector of boost::shared_ptr<Base>:
   Base and Derived members are still reconstructed correctly.
   Derived::shared_from_this() throws a bad_weak_ptr exception.
   This is because enable_shared_from_this::weak_ptr is NOT reconstructed - It is zero.

See test code in attached file that demonstrates both of the above cases."	Bugs	closed	To Be Determined	serialization	Boost 1.53.0	Problem	wontfix	serialization enable_shared_from_this shared_ptr weak_ptr
