I'm embarrassed to to ask this, but maybe someone could interpret this strange compiler error for me:  I am registering a
derived class everywhere that it is archived through a base class pointer:

class MyDerivedClass : public MyBaseClass { … };

class AnotherClass
{
    MyBaseClass *p;
    …
    void serialize(Archive &ar, unsigned int)
    {
        ar.register_type(static_cast<MyDerivedClass *>(NULL));   // compiler error here
        …
       ar & p;
}

At the line above, the error is

error: no matching function for call to ‘boost::archive::xml_oarchive::register_type(AnotherClass:serialize (Archive&, unsigned int) [with Archive = boost::archive::xml_oarchive]::MyDerivedClass*)’

Does the complier think that MyDerivedClass is a member of boost::archive::xml_oarchive?

Im using Boost 1.57 and gcc 4.4.7.   Thanks.
