--- Comment #6 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-9 branch has been updated by Jonathan Wakely <r...@gcc.gnu.org>: https://gcc.gnu.org/g:1228154b8726a3bc903f1967f9b3aac8fd192e46 commit r9-9327-g1228154b8726a3bc903f1967f9b3aac8fd192e46 Author: François Dumont <fdum...@gcc.gnu.org> Date: Fri Jul 3 08:13:19 2020 +0200 libstdc++: Fix [multi]map/[multi]set move constructors noexcept qualification Container move constructors shall not consider their allocator move constructor qualification. For the backport to gcc-9 the _Rb_tree_impl move constructor must be user-provided, because prior to the implementation of P1286R2 in r10-4094, a defaulted special member with a different exception would be deleted. libstdc++-v3/ChangeLog: PR libstdc++/96029 * include/bits/stl_tree.h (_Rb_tree_impl(_Rb_tree_impl&&)): Add noexcept qualification based only on _Compare one. * testsuite/23_containers/map/cons/noexcept_move_construct.cc: Add static asserts. * testsuite/23_containers/multimap/cons/noexcept_move_construct.cc: Likewise. * testsuite/23_containers/multiset/cons/noexcept_move_construct.cc: Likewise. * testsuite/23_containers/set/cons/noexcept_move_construct.cc: Likewise.
