--- Comment #6 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-15 branch has been updated by Patrick Palka <ppa...@gcc.gnu.org>: https://gcc.gnu.org/g:5a29c9147404c0473e009df879e7467ff4948820 commit r15-10062-g5a29c9147404c0473e009df879e7467ff4948820 Author: Patrick Palka <ppa...@redhat.com> Date: Tue Jul 15 15:17:23 2025 -0400 libstdc++: Add missing initializers for __maybe_present_t members [PR119962] Data members of type __maybe_present_t where the conditionally present type might be an aggregate or fundamental type need to be explicitly value-initialized (rather than implicitly default-initialized), so that default-initialization of the containing class always results in an completely initialized object. PR libstdc++/119962 libstdc++-v3/ChangeLog: * include/std/ranges (join_view::_Iterator::_M_outer): Initialize. (lazy_split_view::_OuterIter::_M_current): Initialize.
