There can still be <missing> arguments before the substitution:

template <int N>
void f() {
  f<N + 1>();
}

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

Output:

test.cpp:3:11: error: template instantiation depth exceeds maximum of 900 (use
-ftemplate-depth= to increase the maximum) substituting âtemplate<int N> void
f() [with int N = <missing>]â
  f<N + 1>();
           ^
