Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Last reconfirmed| |2018-09-21 Ever confirmed|0 |1 --- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> --- Proper testcase that actually compiles: #include <type_traits> static_assert(std::is_same<int, long>::value,"eee"); 87386.cc:2:15: error: static assertion failed: eee 2 | static_assert(std::is_same<int, long>::value,"eee"); | Reduced testcase without header dependencies: namespace foo { template<typename> struct test { static constexpr bool value = false; }; } static_assert(foo::test<int>::value, "eee"); 87386.cc:4:15: error: static assertion failed: eee 4 | static_assert(foo::test<int>::value, "eee"); | ^~~ This is a regression, as GCC 7 highlighted the keyword 'static_assert' instead, which makes more sense than just the first token of the condition: 87386.cc:4:1: error: static assertion failed: eee static_assert(foo::test<int>::value, "eee"); ^~~~~~~~~~~~~
