--- Comment #4 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-10 branch has been updated by Jonathan Wakely <r...@gcc.gnu.org>: https://gcc.gnu.org/g:1c4e8a96cd695c03ff85299bf2392476feae99bb commit r10-9673-g1c4e8a96cd695c03ff85299bf2392476feae99bb Author: François Dumont <fdum...@gcc.gnu.org> Date: Mon Jan 20 19:15:43 2020 +0100 libstdc++: Fix unordered containers move constructors noexcept qualification _Hashtable move constructor is wrongly qualified as noexcept(true) regardless of _Equal and _H1 copy constructor qualifications. _Hashtable allocator-aware move constructor is missing its noexcept qualification like the depending unordered containers ones. This backport also includes the changes from r11-8062. libstdc++-v3/ChangeLog: PR libstdc++/96029 * include/bits/hashtable.h (_Hashtable(_Hashtable&& __ht, __node_alloc_type&& __a, true_type)): Add noexcept qualification. (_Hashtable(_Hashtable&&)): Fix noexcept qualification. (_Hashtable(_Hashtable&&, const allocator_type&)): Add noexcept qualification. * include/bits/unordered_map.h (unordered_map(unordered_map&&, const allocator_type&)): Add noexcept qualification. (unordered_multimap(unordered_multimap&&, const allocator_type&)): Likewise. * include/bits/unordered_set.h (unordered_set(unordered_set&&, const allocator_type&)): Likewise. (unordered_multiset(unordered_multiset&&, const allocator_type&)): Likewise. * include/debug/unordered_map (unordered_map(unordered_map&&, const allocator_type&)): Likewise.
