--- Comment #5 from Martin Liška <marxin at gcc dot gnu.org> ---
A valid test-case started to find in r251220:

$ cat ice.ii
namespace a {
template <typename b, typename = b> class c;
template <typename b, typename d> void e(c<b, d> &);
void operator<<(c<char> &f, const char *) { e(f); }
extern c<char> cout;
} // namespace a
int main() { a::cout << ""; }
