#10740: Multi-level containers do not cooperate with address tracking

     Type:  Bugs                              |     Status:  new
Milestone:  To Be Determined                  |  Component:  serialization
  Version:  Boost 1.56.0                      |   Severity:  Problem
 Keywords:  Address tracking, STL containers  |
----------------------------------------------+---------------------------
 Serializing nested sequence containers does not track the object addresses
 correctly. See the attached example.

 Non-sequence containers may also be subject to this bug, I did not check
 them.

 The problem is the push_back in collections_load_imp.hpp:65. If t is
 itself a container, all elements of t get copied, but their address is not
 updated in the archive. In C++11, using emplace() and std::move() should
 solve the problem (did not test this).
