        <pre>Hello,

$cat baz.cpp:
class A {
  template <char N>
  struct Foo {
    static constexpr char Bar() { return 0; }
  };

  using Constants = Foo<1>;

  char var = Constants::Bar();
};

$ clang++ -std=c++17 -c bug.cpp 
bug.cpp:4:27: warning: inline function 'A::Foo<'\x01'>::Bar' is not defined
[-Wundefined-inline]
    static constexpr char Bar() { return 0; }
                          ^
bug.cpp:9:25: note: used here
  char var = Constants::Bar();
                        ^
1 warning generated.

This warning shouldn't be here, should it? Originally discovered with clang-6,
but I've also checked ToT and that also issues a warning. Could be somewhat
related to 18781, but that particular problem seems to be fixed.</pre>
