--- Comment #2 from Martin Sebor <msebor at gcc dot gnu.org> ---
The documentation is also incorrect about the warning being only active with
-ftree-vrp. A small subset of -Warray-bounds is issued even without
optimization. For example the following warning(s) have been issued since GCC
4.1:
$ cat a.c && gcc -S -Wall a.c
int f (void)
{
return __builtin_strlen ("123" + 5);
}
a.c: In function ‘f’:
a.c:3:34: warning: offset ‘5’ outside bounds of constant string
[-Warray-bounds]
3 | return __builtin_strlen ("123" + 5);
| ~~~~~~^~~
a.c:3:10: warning: offset ‘5’ outside bounds of constant string
[-Warray-bounds]
3 | return __builtin_strlen ("123" + 5);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
