 I'm not sure if this is a bug or a limitation of Boost.Serialization.
 I haven't found anything in the documentation saying that this limitation
 exists though.
 it's certainly unexpected if you don't think about serilization internals:

 struct B{
   //Serializable
 };

 struct A{
   B *bptr;

   B b;

   template<class Archive>

   void serialize(Archive &ar,unsigned int){

     ar & bptr;  //error

     ar & b;

   }

 };

 if bptr is pointing to b, the object can not be loaded correctly. I'm not
 sure what actually happens, I guess there is a duplicate created, but bptr
 isnt equal to &b after serialization, as it was before serialization.

 b must be serialized before bptr for this to work.

 testcase attached.
