Managed C++ destructor bug?

[Mark]

I am having a problem using destructors in managed C++ and
would appreciate help in finding a solution.

Thanks

Mark

----------- Error and Test Code -------------------------

The linker throws this error when the code below is built:

testmanagedCxx error LNK2001: unresolved external
symbol "void __cdecl __CxxCallUnwindDtor(void (__thiscall*)
(void *),void *)" (?
__CxxCallUnwindDtor@@$$J0YAXP6EXPAX@Z0@Z)


// This is the main DLL file.

#include "stdafx.h"

#include "testmanagedCxx.h" // the header does not
contain any code

namespace testmanagedCxx
{
public __gc class Base
{
private:
String *s;
public:
Base() { s = new String(L"hello"); }
~Base() { s = 0; }
};

public __gc class Derived : public Base
{
public:
Derived() {}
~Derived() {}
};
}
