Not a bug. Your code is roughly equivalent to this:
----------------------------------
template <class T>
struct Ptr {
    ~Ptr()
      {
        if (ptr_) {
          if (ptr_->unref())
            delete ptr_;
          ptr_ = 0;
        }
      }
};

class Resource {
  public:
    void unref ();
};


class AttributeValue;

class AttributeDefinitionDesc {
  public:
    AttributeDefinitionDesc ();
    Ptr<AttributeValue> p;
};

class AttributeValue : public Resource {};
--------------------------------
You are using AttributeValue in AttributeDefinitionDesc before the type is
fully declared. In AttributeDefinitionDesc, you are instantiating 
Ptr<AttributeValue>, which requires knowledge of AttributeValue, which isn't
available yet at that point. You need to reorder your class declarations.
