... the program is ill-formed; no diagnostic required.
                               ^^^^^^^^^^^^^^^^^^^^^^^
GCC doesn't immediately see that the first operand of ?: is zero or non-zero in
that function, so assumes it could be either zero or non-zero and doesn't
diagnose, you get diagnostics only when you are actually using the function in
some constexpr var initializer or other context where a constant expression is
required.
