From: "vanyacpp at gmail dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug sanitizer/99418] sanitizer checks for accessing multidimentional VLA-array Date: Tue, 09 Mar 2021 08:54:22 +0000 [thread overview] Message-ID: <bug-99418-4-ltt6qu84Y7@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-99418-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99418 --- Comment #8 from Ivan Sorokin <vanyacpp at gmail dot com> --- If I understand #c5 correctly the minimal reproducer should be this: void g(int&); void f() { int a[10]; int& p = a[10]; // (1) g(a[10]); // (2) } Both (1) and (2) are undefined and -fsanitize=bounds can help checking this.
