--- Comment #6 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Jonathan Wakely <r...@gcc.gnu.org>: https://gcc.gnu.org/g:1a9681e60964c7f7ce0892e14745e6dcf6100157 commit r12-8660-g1a9681e60964c7f7ce0892e14745e6dcf6100157 Author: Jonathan Wakely <jwak...@redhat.com> Date: Thu Jul 28 20:55:51 2022 +0100 libstdc++: Tweak common_iterator::operator-> return type [PR104443] This adjusts the return type to match the resolution of LWG 3672. There is no functional difference, because decltype(auto) always deduced a value anyway, but this makes it simpler and consistent with the working draft. libstdc++-v3/ChangeLog: PR libstdc++/104443 * include/bits/stl_iterator.h (common_iterator::operator->): Change return type to just auto. (cherry picked from commit b5f5d1b36edbcd7d923f2e2653e54e52637c715b)
