The standard rquires that std::make_optional is constrained similarly to the std::optional constructors, which our implementation fails to do. As a conforming extension this also adds a noexcept-specifier to each std::make_optional overload. libstdc++-v3/ChangeLog: * include/std/optional (make_optional): Add enable_if constraints and noexcept-specifier to each overload. * testsuite/20_util/optional/make_optional-2.cc: New test. |
