//  Test that the compiler catches uninitialized references. Given that
//  references are conceptually an object rename, they must be initialized
//  to something (see Stroustrap, p. 56). At best, g++ gives a warning,
//  at worst, it says nothing at all.

    void some_function()
    {
        int&  a_ref;                     // g++ gives a warning
     }

    class erroneous {  
        int&   a_ref;                    // g++ says nothing
    };

Personally, I think both these cases should be an error, but a warning is
better than nothing. Sorry if this has been posted before.
