--- Comment #10 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-13 branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:c7f51dc49399023830787e5eec18649b5c2fabc5 commit r13-9584-gc7f51dc49399023830787e5eec18649b5c2fabc5 Author: Jakub Jelinek <ja...@redhat.com> Date: Sat Jan 25 10:15:24 2025 +0100 c++: Only destruct elts of array for new expression if exception is thrown during the initialization [PR117827] The following testcase r12-6328, because the elements of the array are destructed twice, once when the callee encounters delete[] p; and then second time when the exception is thrown. The array elts should be only destructed if exception is thrown from one of the constructors during the build_vec_init emitted code in case of new expressions, but when the new expression completes, it is IMO responsibility of user code to delete[] it when it is no longer needed. So, the following patch uses the cleanup_flags argument to build_vec_init to get notified of the flags that need to be changed when the expression is complete and build_disable_temp_cleanup to do the changes. 2025-01-25 Jakub Jelinek <ja...@redhat.com> PR c++/117827 * init.cc (build_new_1): Pass address of a make_tree_vector () initialized gc tree vector to build_vec_init and append build_disable_temp_cleanup to init_expr from it. * g++.dg/init/array66.C: New test.
