------------------------------+------------------------
 Please consider the following code, this crashes with slist but works just
 fine if I replace slist with list. Also flat_map crashes but std::map
 works fine. Am I doing something gross or is there a bug here?

 #include <iostream>
 #include <boost/container/flat_map.hpp>
 #include <map>
 //#include <boost/intrusive/list.hpp>
 #include <boost/intrusive/slist.hpp>

 using namespace boost::intrusive;

 struct m : public slist_base_hook<>
 {
   int n;
   public:
     m(int k) : n(k) { }
 };

 int main()
 {
   boost::container::flat_map<int, slist<m, cache_last<true> > > c1;
   std::map<int, slist<m, cache_last<true> > > c2;
   m* m1 = new m(22);
   c1[1].push_back(*m1);

   m* tt = new m(99);
   c2[1].push_back(*tt);
 }
