     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  container
  Version:  Boost 1.64.0      |   Severity:  Showstopper
 Keywords:                    |
------------------------------+---------------------------
 Code that uses boost::container::flap_map fails to compile on gcc4.8.5
 with -std=c++1 when BOOST_MOVE_USE_STANDARD_LIBRARY_MOVE is defined, with
 the following compile error:

 boost/move/unique_ptr.hpp: In constructor 'boost::movelib::unique_ptr<T,
 D>::unique_ptr(boost::movelib::unique_ptr<T, D>&&)':
 boost/move/unique_ptr.hpp:528:29: error: 'move_if_not_lvalue_reference' is
 not a member of 'boost'
        : m_data(u.release(),
 ::boost::move_if_not_lvalue_reference<D>(u.get_deleter()))
                              ^
 boost/move/unique_ptr.hpp:528:68: error: expected primary-expression
 before '>' token
        : m_data(u.release(),
 ::boost::move_if_not_lvalue_reference<D>(u.get_deleter()))

 I was able to workaround this by passing in
 -DBOOST_MOVE_MAKE_UNIQUE_HPP_INCLUDED on the commandline to gcc, which
 effectively inhibits boost/move/make_unique.hpp from being included.

 The fact the above workaround worked at all seems to suggest that
 container/detail/flat_tree.hpp has no dependency on
 boost/move/make_unique.hpp.
