 in file: python/detail/wrapper_base.hpp:64

 function:

 namespace wrapper_base_ // ADL disabler
   {
     template <class T>
     inline PyObject*
     owner_impl(T const volatile* x, mpl::true_)
     {
         if (wrapper_base const volatile* w = dynamic_cast<wrapper_base
 const volatile*>(x)) /*this dynamic cast fails */
         {
             printf("dynamic_cast: OK\n");
             return wrapper_base_::get_owner(*w);
         }
         printf("dynamic_cast: FAIL %s:%p\n",
 boost::python::type_id<wrapper_base>().name(), x);
         return 0;
     }


 this dynamic cast fail:
 " dynamic_cast<wrapper_base const volatile*>(x) "  when type of x not is
 not in the current module, this cause boost create a new PyObject for the
 c++ pointer.
