--- Comment #16 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Andrew Pinski <pins...@gcc.gnu.org>: https://gcc.gnu.org/g:16319f8fba6c049d743046488588f40da2349048 commit r12-10432-g16319f8fba6c049d743046488588f40da2349048 Author: Andrew Pinski <quic_apin...@quicinc.com> Date: Wed Feb 21 20:12:21 2024 -0800 warn-access: Fix handling of unnamed types [PR109804] This looks like an oversight of handling DEMANGLE_COMPONENT_UNNAMED_TYPE. DEMANGLE_COMPONENT_UNNAMED_TYPE only has the u.s_number.number set while the code expected newc.u.s_binary.left would be valid. So this treats DEMANGLE_COMPONENT_UNNAMED_TYPE like we treat function paramaters (DEMANGLE_COMPONENT_FUNCTION_PARAM) and template paramaters (DEMANGLE_COMPONENT_TEMPLATE_PARAM). Note the code in the demangler does this when it sets DEMANGLE_COMPONENT_UNNAMED_TYPE: ret->type = DEMANGLE_COMPONENT_UNNAMED_TYPE; ret->u.s_number.number = num; Committed as obvious after bootstrap/test on x86_64-linux-gnu PR tree-optimization/109804 gcc/ChangeLog: * gimple-ssa-warn-access.cc (new_delete_mismatch_p): Handle DEMANGLE_COMPONENT_UNNAMED_TYPE. gcc/testsuite/ChangeLog: * g++.dg/warn/Wmismatched-new-delete-8.C: New test. Signed-off-by: Andrew Pinski <quic_apin...@quicinc.com> (cherry picked from commit 1076ffda6ce5e6d5fc9577deaf8233e549e5787a)
