The following code sample is compiled by several other compilers. Gcc compiles the following example, when the function f is put into the global scope.
The example can also be compiled, when v has only a single template parameter.



template <class T1, class T2>
class v { };

class c2 {
    void f(const v<int, int> &t = v<int, int>()) { }
};

int main() { }



The code cannot be compiled by gcc 3.4, 4.1.2 and 4.2
In the example it is of course essential that t is a _constant_ reference.
