[Bug c++/20153] New: ICE when C++ template function contains anonymous union

["us15 at os dot inf dot tu-dresden dot de" <gcc-bugzilla at gcc dot gnu dot org>]

The following program causes an internal compiler error when compiled with
gcc-3.4.3 or gcc-4.0 (CVS):

template <typename T>
class C
{
    public:
        void foo();
};

template <typename T>
void
C<T>::foo()
{
    union {
        struct {
        };
    };
};

int main()
{
    return 0;
}
