During instantiation they are handled later, but during the parsing keeping the structured bindings type dependent when they shouldn't be changes behavior. The following patch calls cp_finish_decomp even from do_range_for_auto_deduction. The patch regresses the OpenMP g++.dg/gomp/for-21.C test (3 errors are gone), I'll post an incremental patch for it momentarily. 2022-12-02 Jakub Jelinek <jakub@redhat.com> PR c++/84469 * parser.cc (do_range_for_auto_deduction): Add DECOMP_FIRST_NAME and DECOMP_CNT arguments. Call cp_finish_decomp if DECL is a structured binding. (cp_parser_range_for): Adjust do_range_for_auto_deduction caller. (cp_convert_omp_range_for): Likewise. * g++.dg/cpp1z/decomp56.C: New test. * g++.dg/gomp/pr84469.C: New test.
