--- Comment #2 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:815baade9a07d361b1daa1dcfbbda2a79f3ebb52 commit r11-4538-g815baade9a07d361b1daa1dcfbbda2a79f3ebb52 Author: Jakub Jelinek <ja...@redhat.com> Date: Thu Oct 29 16:27:01 2020 +0100 c++: Diagnose constexpr delete [] new int; and delete new int[N]; [PR95808] This patch diagnoses delete [] new int; and delete new int[1]; in constexpr contexts by remembering IDENTIFIER_OVL_OP_FLAGS (DECL_NAME (fun)) & OVL_OP_FLAG_VEC from the operator new and checking it at operator delete time. 2020-10-29 Jakub Jelinek <ja...@redhat.com> PR c++/95808 * cp-tree.h (enum cp_tree_index): Add CPTI_HEAP_VEC_UNINIT_IDENTIFIER and CPTI_HEAP_VEC_IDENTIFIER. (heap_vec_uninit_identifier, heap_vec_identifier): Define. * decl.c (initialize_predefined_identifiers): Initialize those identifiers. * constexpr.c (cxx_eval_call_expression): Reject array allocations deallocated with non-array deallocation or non-array allocations deallocated with array deallocation. (non_const_var_error): Handle heap_vec_uninit_identifier and heap_vec_identifier too. (cxx_eval_constant_expression): Handle also heap_vec_uninit_identifier and in that case during initialization replace it with heap_vec_identifier. (find_heap_var_refs): Handle heap_vec_uninit_identifier and heap_vec_identifier too. * g++.dg/cpp2a/constexpr-new15.C: New test.
