Milestone:  To Be Determined            |  Component:  serialization
  Version:  Boost 1.62.0                |   Severity:  Problem

----------------------------------------+---------------------------
 Consider two classes, Father and Child, with a circular dependency. Father
 contains a Child member, and Child contains a pointer to Father.

 There is a way to serialize and deserialize this structure in such a way
 that an extra object of type Child is created. I believe that
 pointer_conflict should be thrown during serialization instead.

 The created XML archive (see attachment) is consistent, so the extra
 object is created during deserialization.

 I observed this behavior in 1.57 and 1.62.
