Andrew Sutton <andrew.n.sutton at gmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |andrew.n.sutton at gmail dot com --- Comment #3 from Andrew Sutton <andrew.n.sutton at gmail dot com> --- I think this error is correct (i.e., there is no defect in trunk): 48 | static_assert(S2<int>::f()); // Bogus non-error The requirements of this declaration: static constexpr bool f() requires bool_<true> && true { return true; } are incomparable with those of the overloads requiring Foo and Bar. The atomic constraints bool_<true> and true are not identical to those pulled in by the normalization of Same_impl.
