I have solve the problem.
I missing terminate function.
Modify source file
int main(int argc, char* argv[])
    {
    Human human;
    human.initiate();
+ human.terminate();
    return 0;
    }

  I wrote a simple code.
  source file:
  #include <boost/statechart/event.hpp>
  #include <boost/statechart/transition.hpp>
  #include <boost/statechart/simple_state.hpp>
  #include <boost/statechart/state.hpp> 
  #include <boost/statechart/state_machine.hpp>
  #include <boost/statechart/custom_reaction.hpp>
  #include <boost/shared_ptr.hpp>
  #include <boost/weak_ptr.hpp>
  #include <boost/mpl/list.hpp> 
  #include <iostream>
  #include <string>
  using namespace std;
  namespace sc=boost::statechart;
  namespace mpl=boost::mpl;

  struct EvtEat:sc::event<EvtEat>{};
  struct EvtStop:sc::event<EvtStop>{}; 

  struct Eating;
  struct Idle;

  class Human:public sc::state_machine< Human, Idle >
      {
      public:
          void show(void)
              {
              cout<<__FUNCTION__<<endl; 
              }
      };

  struct Idle:sc::state< Idle, Human >
      {
      Idle(my_context ctx):my_base(ctx)
          {
          context<Human>().show(); //ok
          };
      ~Idle(void)
          {
          context<Human>().show(); //assert failed
          };
      };

  struct Eating:sc::state< Eating, Human >
      {
      Eating(my_context ctx):my_base(ctx)
          {
          }; 
      ~Eating(void)
          {
          context<Human>();
          }
      };

  int main(int argc, char* argv[])
      {
      Human human;
      human.initiate();
      return 0;
      }


  /*
  In debug mode.It output

  Human::show
  Assertion failed: dynamic_cast<Target>(x) == x, file p:\programme\libs\boost\include\boost-1_35\boost\cast.hpp, line 97
  */

  Why does it assert failed and how to modify the source? 

  Thank you.
