     Type:  Bugs                                 |  Component:  phoenix
Milestone:  To Be Determined                     |   Severity:  Problem
  Version:  Boost 1.60.0                         |

-------------------------------------------------+-------------------------
 Boost 1.60 introduced the header
 boost/phoenix/stl/algorithm/detail/std_unordered_set_or_map_fwd.hpp.

 When building on Linux with libstdc++ debug mode (-DGLIBCXX_DEBUG) this
 causes ambiguous references to the forward-declared classes because in
 libstdc++ side, they now live in the std::__debug namespace instead.

 The following test cases triggers it :


 {{{

 #include <boost/spirit/include/phoenix.hpp>
 #include <unordered_map>

 void f()
 {
         std::unordered_map<int, float> map;
 }
 }}}

 when built with

 {{{ g++ -std=c++11 -D_GLIBCXX_DEBUG=1 -c problem.cpp }}}
