[Boost-users] Boost.Serialization not building

Dear all,

we just upgrade to Boost 1.41 and get a compile error in Boost.Serialization:

1>c:\work sdk\boost_1_41_0\boost/archive/shared_ptr_helper.hpp(114) : error 
C2440: 'return' : cannot convert from 'const 
boost::serialization::extended_type_info_typeid<T>' to 'const 
boost::serialization::extended_type_info *'

There was already a discussion about this on the newsgroup but no solution was 
posted: http://thread.gmane.org/gmane.comp.lib.boost.user/52384/focus=52390

The case is easy reproducable:

struct Foo
{
    //virtual ~Foo(){}
};

struct Foo2 : public Foo
{
    template <class Archive>
    void serialize(Archive& /*ar*/, const unsigned int /*version*/)
    {
    }
};

struct Bla
{
    template <class Archive>
    void serialize(Archive& ar, const unsigned int /*version*/)
    {
        ar & BOOST_SERIALIZATION_NVP(m_ptrFoo2);
    }

    boost::shared_ptr<Foo2> m_ptrFoo2;
};

void F()
{
    std::stringstream sstr;
    Bla               bla;

    boost::archive::xml_iarchive ia(sstr);
  
    ia >> boost::serialization::make_nvp("bla", bla);
}

Can somebody help? Adding a virtual dtor does remove the problem (and is 
exactly the difference with 'test_shared_ptr.cpp') but this is unwanted.
