Hi, all!

I didn't find yet solution for this problem! Somebody knows where is a
catch?
Looks like "operator =" or copy constructor not implemented in one of
internal templates....

Thanks in advance

class CMyBase;
typedef auto_ptr<CMyBase> MyBasePtr;
typedef map<int, MyBasePtr> MAP_BASE;

class CMyBase
{
public:
CMyBase()
{ }
virtual ~CMyBase()
 { }
virtual MyBasePtr Clone(void) const
 { return MyBasePtr(new CMyBase()); }
virtual MyBasePtr Test()
{
 MAP_BASE _map2;
 _map2[1] = m_map.begin()->second->Clone();// Compiler error occured:
C2558: class 'std::auto_ptr<_Ty>' : no

//copy constructor available or copy constructor is declared 'explicit'
}
private:
 MAP_BASE m_map;
};
