From: "yann at droneaud dot fr" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug middle-end/110292] undefined value due to strict aliasing without warning Date: Sat, 17 Jun 2023 05:46:12 +0000 [thread overview] Message-ID: <bug-110292-4-8fZee56PYw@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-110292-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110292 --- Comment #5 from Yann Droneaud <yann at droneaud dot fr> --- Hi, Thanks a lot for the quick analysis of my issue. (In reply to Andrew Pinski from comment #4) > Note -Wstrict-aliasing=1 actually does warn: OK, and -Wall enables -Wstrict-aliasing which defaults to -Wstrict-aliasing=3, I'm sorry I haven't tried to use lower values ... https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html#index-Wstrict-aliasing (In reply to Andrew Pinski from comment #2) > aliasing violations are known not to be warned about nor have a runtime > sanitizer either. Is there any other tool that would reliably detect such issues ? Regards
