--- Comment #22 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Author: jakub Date: Tue Dec 3 19:27:47 2019 New Revision: 278945 URL: https://gcc.gnu.org/viewcvs?rev=278945&root=gcc&view=rev Log: PR c++/91369 * constexpr.c (struct constexpr_global_ctx): Add cleanups member, initialize it in the ctor. (cxx_eval_constant_expression) <case TARGET_EXPR>: If TARGET_EXPR_SLOT is already in the values hash_map, don't evaluate it again. Put TARGET_EXPR_SLOT into hash_map even if not lval, and push it into save_exprs too. If there is TARGET_EXPR_CLEANUP and not CLEANUP_EH_ONLY, push the cleanup to cleanups vector. <case CLEANUP_POINT_EXPR>: Save outer cleanups, set cleanups to local auto_vec, after evaluating the body evaluate cleanups and restore previous cleanups. <case TRY_CATCH_EXPR>: Don't crash if the first operand is NULL_TREE. (cxx_eval_outermost_constant_expr): Set cleanups to local auto_vec, after evaluating the expression evaluate cleanups. * g++.dg/cpp2a/constexpr-new8.C: New test.
