Synopsis: [3.4 regression] Parser bug

State-Changed-From-To: open->closed
State-Changed-By: bangerth
State-Changed-When: Wed Jan 22 21:44:35 2003
State-Changed-Why:
    You need to write
         typename Foo<Dim>::Bar(1);
    (note the "typename").
    
    Also, there is no need to ping gcc@gcc.gnu.org for each bug
    you find. The people who can fix bugs, and the people like
    me who filter them, are quite comfortable with reading
    gcc-bugs (where new reports are automatically posted), and
    with searching the database.

The following testcase is rejected by the new C++ parser
and accepted by earlier g++ and EDG in strict mode.

template <int Dim>
struct Foo {
        struct Bar {
                Bar(int);
        };
};

template <int Dim>
struct Baz : public Foo<Dim> {
        void foo()
        {
                Foo<Dim>::Bar(1);
        }
};

int main()
{
        Baz<3> baz;
        baz.foo();
        return 0;
}
