--- Comment #7 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:60954a06ceb1598d86763e5504d8e1b874b6bd6a commit r12-8618-g60954a06ceb1598d86763e5504d8e1b874b6bd6a Author: Jason Merrill <ja...@redhat.com> Date: Mon Jul 25 11:13:31 2022 -0400 c++: aggregate prvalue as for range [PR106230] Since my PR94041 work on temporary lifetime in aggregate initialization, we end up calling build_vec_init to initialize the reference-extended temporary for the artificial __for_range variable. And build_vec_init uses finish_for_stmt to implement its loop. That function assumes that if __for_range is in current_binding_level, we're finishing a range-for, and we should fix up the variable as it goes out of scope. But when called from build_vec_init we aren't finishing a range-for, and do_poplevel doesn't remove the variable from scope because stmts_are_full_exprs_p is false. So let's check that here as well, and leave the DECL_NAME alone. PR c++/106230 gcc/cp/ChangeLog: * semantics.cc (finish_for_stmt): Check stmts_are_full_exprs_p. gcc/testsuite/ChangeLog: * g++.dg/cpp0x/range-for38.C: New test.
