--- Comment #1 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Tomasz Kaminski <tkami...@gcc.gnu.org>: https://gcc.gnu.org/g:3b32473d3e40d816e4ba280f8a58f44957219681 commit r15-8291-g3b32473d3e40d816e4ba280f8a58f44957219681 Author: Tomasz KamiÅski <tkami...@redhat.com> Date: Tue Mar 18 17:32:40 2025 +0100 libstdc++: Cast difference_type for insert_range unordered non-unique containers [PR119358] ranges::distance may produce an integer-like class type (ranges::__detail::__max_diff_type) that is only explicitly convertible to other integer types, so the result needs to be casted to containers size_type. PR libstdc++/119358 libstdc++-v3/ChangeLog: * include/bits/unordered_map.h (unordered_multimap::insert_range): Cast ranges::distance to size_type before passing to _M_rehash_insert. * include/bits/unordered_set.h (unordered_multiset::insert_range): Same as unordered_multimap::insert_range. * testsuite/23_containers/unordered_multimap/cons/from_range.cc: New tests. * testsuite/23_containers/unordered_multiset/cons/from_range.cc: New tests.
