[Bug c++/69903] Function template specialization with CRTP-class causes compiler segfault

--- Comment #6 from Patrick Palka <ppalka at gcc dot gnu.org> ---
Smaller test case:

struct A {
  template <int i>
  static void f() { };
};

struct B : A { };

template<>
void B::f<0>() { };

int main() {
  B::f<0> ();
}


If f is made non-static then the compiler rejects the specialization and
there's no ICE.

And if "void B::f<0>" is replaced with "void A::f<0>" then the code is accepted
without errors.
