<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>
