 Compiler gcc-5.4.0.

 {{{
 #include <boost/type_traits.hpp>

 static const bool is_enum = boost::is_enum<std::pair<int, int> >::value;

 #include <boost/container/flat_map.hpp>

 boost::container::flat_map<int, int> m;
 }}}

 error is:
 {{{
 /boost/boost/container/detail/pair.hpp:433:8: error: partial
 specialization of ‘struct boost::is_enum<std::pair<_T1, _T2> >’ after
 instantiation of ‘struct boost::is_enum<std::pair<int, int> >’
 [-fpermissive]
 }}}

 Version 1.59.0 compiles fine.
