#10382: 1.56.0 Graph adjacency_list has compile errors on g++ 4.6.4
---------------------------------------------+-------------------------
 Reporter:  Conrad Mercer <conrad.mercer@…>  |      Owner:  jewillco
     Type:  Bugs                             |     Status:  new
Milestone:  To Be Determined                 |  Component:  graph
  Version:  Boost 1.56.0                     |   Severity:  Showstopper
 Keywords:  compile error                    |
---------------------------------------------+-------------------------
 The following code will generate compile errors on g++ 4.6.4 but works on
 g++ 4.7 and 4.8. The problem looks to be in
 detail/adjacency_list.hpp:319-21 where the = default; specification is
 unable to generate a valid implementation so the move operators become
 implicitly deleted.

 {{{
 #include "boost/graph/adjacency_list.hpp"

 int main(int argc, char** argv)
 {
   using boost::adjacency_list;
   using boost::vecS;
   using boost::directedS;
   typedef adjacency_list<vecS, vecS, directedS, boost::default_color_type>
 Graph;

   std::vector< std::pair<int, int> > testVec;
   auto graph = Graph( begin(testVec), end(testVec), testVec.size());

   return 0;
 }
 }}}
