--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Jonathan Wakely from comment #1) > This is broken in two ways, you need to include both <algorithm> *and* > <vector> for this program. Actually three ways. There is no guarantee that std::vector's iterators have namespace std as an associated namespace, so begin(v) and end(v) are not guaranteed to find std::begin and std::end. You should qualify them or add using declarations.
