--- Comment #10 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-14 branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:08bfa32ae92e36a791ebdefd063b4f2616cd6f80 commit r14-11297-g08bfa32ae92e36a791ebdefd063b4f2616cd6f80 Author: Jakub Jelinek <ja...@redhat.com> Date: Fri Feb 7 17:08:39 2025 +0100 c++: Fix up name independent decl in structured binding handling in range for [PR115586] cp_parser_range_for temporarily reverts IDENTIFIER_BINDING changes to hide the decls from the structured bindings from lookup during parsing of the expression after : If there are 2 or more name independent decls, we undo IDENTIFIER_BINDING for the same name multiple times, even when just one has been added (with a TREE_LIST inside of it as decl). The following patch fixes it by handling the _ name at most once, the later loop will DTRT then and just reinstall the temporarily hidden binding with the TREE_LIST in there. 2025-02-07 Jakub Jelinek <ja...@redhat.com> PR c++/115586 * parser.cc (cp_parser_range_for): For name independent decls in structured bindings, only push the name/binding once per structured binding. * g++.dg/cpp26/name-independent-decl9.C: New test. * g++.dg/cpp26/name-independent-decl10.C: New test.
