this code compile under visual studio 6
C:\Program Files\Microsoft Visual Studio .NET
2003\Vc7\include\xmemory(42): error C2558:

class 'std::auto_ptr<_Ty>' : no copy constructor available or copy
constructor is declared 'explicit'
with
[
_Ty=myClass
]

// TEMPLATE FUNCTION _Construct
template<class _T1,
class _T2> inline
void _Construct(_T1 _FARQ *_Ptr, const _T2& _Val)
{ // construct object at _Ptr with value _Val
new ((void _FARQ *)_Ptr) _T1(_Val);
}

it tries to construct an abstract class......
