**Newbie with managed C++**

I'm trying to wrap an unmanaged C++ class in a managed C++ class library.
When I instantiate the wrapper class it's ctor calls the ctor on the
unmanaged class and at that point I get the exception:
"An unhandled exception of type 'System.StackOverflowException' occurred in
suabwrapper.dll"

I have been able to reproduce this with an unmanaged class that is VERY
simple:
class CTest

{

public:

     CTest(){ m_id = 1; }

     ~CTest(){}

     int GetID(){ return m_id; };

private:

     int m_id;

};

In my managed class I have a CTest* member that I assign to a new CTest() in
the managed class' ctor:

CSUABWrapper()

{

     m_pTest = new CTest();

}

Once the CTest ctor is called (I can't step into the code for some reason) I
get the exception.
Anyone know what could be going on?  Any ideas??

Thanks,
Steve
