If I do not register base classe <Modul>, nor in serializing code nor in
deserializing code:
It compliles and serializing runs and creates perfect archive.
But when I try to deserialize the archive I get a runtime error:

terminate called after throwing an instance of
'boost::archive::archive_exception'
  what():  stream error

How do I de/serialize: I created a class and use a vector of base class
pointers:

class LogElement
{
  public:
    LogElement();
    virtual ~LogElement(){};

    std::vector<Modul*> Module;

  private:
    friend class boost::serialization::access;

    template <typename Archive>
    void serialize(Archive &ar, const unsigned int version)
    {
      ar & boost::serialization::make_nvp("Module", Module);
    };
};

In Module are pointers to objects of derived classes. Is it a problem?
