#11829: Order of elements with same key in multimap not preserved
------------------------------+---------------------------
 Reporter:  boost@…           |      Owner:  ramey
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  serialization
  Version:  Boost 1.59.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+---------------------------
 The hinting in load_map_collection from boost/serialization/map.hpp
 destroys the relative order of elements with the same key. Since C++11 one
 can reconstruct multimaps where the elements preserve the original order.
 However, one has to use the multimap insertions without hinting. A quick
 fix would be to drop hinting for multimaps whereas for maps it can still
 be used. Possibly also hinting with the end pointer would work.
