[Bug c++/34550] New: reference data template args appear to be broken in 4.2.1 ?

[johill at lanl dot gov]

Code below builds w/o issues using earlier gcc and other compilers -
thought you might want to know about the issue. 

Thanks in adv, and happy holidays.

template < class T, const int & R >
class Cat {
public:
        Cat ( int );
};

template < class T, int & R >
Cat < T, R > ::  Cat ( int )
{
}

extern const int myConstant = 4;

int main ()
{
        Cat < float, myConstant > cat ( 2 );
        return 0;
}

bash-3.00$ g++ cat.cpp
cat.cpp:13: error: invalid use of incomplete type 'class Cat<T, R>'
cat.cpp:6: error: declaration of 'class Cat<T, R>'
bash-3.00$ g++ -v
