#12256: boost::container::set<std::pair<int,int>>::insert cause compilation error
in debug configuration in Visual Studio 2012

 Reporter:  anonymous         |      Owner:  igaztanaga
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  container
  Version:  Boost 1.61.0      |   Severity:  Showstopper
 Keywords:                    |
------------------------------+-------------------------
 Here is the example code
 {{{
         boost::container::set<std::pair<int,int>> s;
         std::pair<int,int> p(0, 0);
         s.insert(p);
 }}}
 It outputs a several pages long template error starting as
 {{{

 Same code compiles correctly in release configuration.
 And it compiles correctly in boost 1.59 in all configurations.

 Marking it as Showstopper as it breaks a lot of our code.

 To reproduce - create a new VS2012 project with default settings.
 I didn't test it on other versions of Visual Studio.
