Comment:

 This is not a bug. Construction of boost::python::object from a raw
 pointer is not supported. Try this (didn't try to compile this, but I
 tested the idea):

 {{{
 boost::python::object create(char c)
 {
     if(c == 'X')
         return boost::python::object(boost::shared_ptr<X>(new X));
     else if(c == 'Y')
         return boost::python::object(boost::shared_ptr<Y>(new Y));
     else if(c == 'Z')
         return boost::python::object(boost::shared_ptr<Z>(new Z));
     else
         throw std::exception("The function argument must be 'X', 'Y' or
 'Z'.");
 }
 }}}

 with

 {{{
     class_<X, boost::shared_ptr<X>, noncopyable>("X").def("hello",
 &X::hello);

 }}}


 etc.
