--- Comment #6 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jonathan Wakely <r...@gcc.gnu.org>: https://gcc.gnu.org/g:b25b101bc380004b82e25d2b1ef306856c75d864 commit r15-3124-gb25b101bc380004b82e25d2b1ef306856c75d864 Author: Jonathan Wakely <jwak...@redhat.com> Date: Wed Aug 21 21:19:46 2024 +0100 libstdc++: Make std::vector<bool>::reference constructor private [PR115098] The standard says this constructor should be private. LWG 4141 proposes to remove it entirely. We still need it, but it doesn't need to be public. For std::bitset the default constructor is already private (and never even defined) but there's a non-standard constructor that's public, but doesn't need to be. libstdc++-v3/ChangeLog: PR libstdc++/115098 * include/bits/stl_bvector.h (_Bit_reference): Make default constructor private. Declare vector and bit iterators as friends. * include/std/bitset (bitset::reference): Make constructor and data members private. * testsuite/20_util/bitset/115098.cc: New test. * testsuite/23_containers/vector/bool/115098.cc: New test.
