--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Jan Polasek from comment #0) > https://godbolt.org/z/ozf1MbG3n shows this code works fine under MSVC. You don't try to use foo afterwards. Once you do, MSVC will have an ICE. try: ``` #include <source_location> #include <utility> template <int i, class = void> struct foo; // Two following two specializations are different, yet gcc errors out, // claiming they are the same. #line 9 template <int i> struct foo<i, std::enable_if_t<i == std::source_location::current().line()>> { static constexpr int num = i; }; #line 14 template <int i> struct foo<i, std::enable_if_t<i == std::source_location::current().line()>> { static constexpr int num = i; }; int main(void) { foo<9> t; foo<14> t; } ``` So I don't know if this is valid or not.
