--- Comment #2 from Daniel Krügler <daniel.kruegler at googlemail dot com> --- (In reply to Jonathan Wakely from comment #1) > Trunk doesn't give the same errors, but fails two of the assertions: > > n.cc:30:1: error: static assertion failed: > static_assert(std::is_nothrow_constructible<X>::value, ""); The reason seems to be that the compiler makes this a deleted function, arguing "'X::X() noexcept' is implicitly deleted because its exception-specification does not match the implicit exception-specification 'noexcept (<uninstantiated>)' X() noexcept = default;" This looks incorrect to me.
