From: "schwab@linux-m68k.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug sanitizer/104929] UBSAN: false positive with sprintf Date: Tue, 15 Mar 2022 09:42:57 +0000 [thread overview] Message-ID: <bug-104929-4-5KkxmJfFv8@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-104929-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=104929 --- Comment #2 from Andreas Schwab <schwab@linux-m68k.org> --- I think the point here is that s is not guaranteed to be non-NULL. You can add if (s == 0) __builtin_unreachable(); to suppress the warning.
