From: "redi at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug libstdc++/64814] std::copy_n advances InputIterator one *less* time than necessary. Date: Tue, 27 Jan 2015 16:29:00 -0000 [thread overview] Message-ID: <bug-64814-4-NOs7VDrnul@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-64814-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64814 --- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> --- The current behaviour is decades old, coming from the copy_n in the SGI STL, and like the standard https://www.sgi.com/tech/stl/copy_n.html says nothing about postconditions for the input iterator. Note http://cplusplus.github.io/LWG/lwg-active.html#2242 though.
