--- Comment #25 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-11 branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:19dcea67ac40cfdeb396fa264ebbe04fbe61fdc0 commit r11-9222-g19dcea67ac40cfdeb396fa264ebbe04fbe61fdc0 Author: Richard Biener <rguent...@suse.de> Date: Mon Oct 11 16:06:03 2021 +0200 middle-end/101480 - overloaded global new/delete The following fixes the issue of ignoring side-effects on memory from overloaded global new/delete operators by not marking them as effectively 'const' apart from other explicitely specified side-effects. This will cause FAIL: g++.dg/warn/Warray-bounds-16.C -std=gnu++1? (test for excess errors) because we now no longer statically see the initialization loop never executes because the call to operator new can now clobber 'a.m'. This seems to be an issue with the warning code and/or ranger so I'm leaving this FAIL to be addressed as followup. 2021-10-11 Richard Biener <rguent...@suse.de> PR middle-end/101480 * gimple.c (gimple_call_fnspec): Do not mark operator new/delete as const. * g++.dg/torture/pr10148.C: New testcase. (cherry picked from commit 09a0affdb0598a54835ac4bb0dd6b54122c12916)
