--- Comment #4 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:c4b8949a3ad0a2259388841f3c833876a19bd2a2 commit r12-9131-gc4b8949a3ad0a2259388841f3c833876a19bd2a2 Author: Jakub Jelinek <ja...@redhat.com> Date: Wed Dec 21 09:05:27 2022 +0100 openmp: Don't try to destruct DECL_OMP_PRIVATIZED_MEMBER vars [PR108180] DECL_OMP_PRIVATIZED_MEMBER vars are artificial vars with DECL_VALUE_EXPR of this->field used just during gimplification and omp lowering/expansion to privatize individual fields in methods when needed. As the following testcase shows, when not in templates, they were handled right, but in templates we actually called cp_finish_decl on them and that can result in their destruction, which is obviously undesirable, we should only destruct the privatized copies of them created in omp lowering. Fixed thusly. 2022-12-21 Jakub Jelinek <ja...@redhat.com> PR c++/108180 * pt.cc (tsubst_expr): Don't call cp_finish_decl on DECL_OMP_PRIVATIZED_MEMBER vars. * testsuite/libgomp.c++/pr108180.C: New test.
