Milestone:  To Be Determined  |  Component:  container
  Version:  Boost 1.57.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+------------------------
 There is a problem with the value_type typedef. It is a typedef of
 std::pair<Key, Value> but shouldn't it be std::pair<const Key, Value>?

 typedef boost::unordered_map<int, string>       Int2StringUmap;
 typedef boost::container::flat_map<int, string> Int2StringFmap;

 static_assert(std::is_same<Int2StringUmap::value_type, std::pair<const
 int, string>>::value, ""); //ok
 static_assert(std::is_same<Int2StringFmap::value_type, std::pair<const
 int, string>>::value, ""); //not ok

 Maybe already reported, but I couldn't find it in the svn.
