--- Comment #6 from Martin Sebor <msebor at gcc dot gnu.org> ---
I can reproduce the problem with the following test case. Let me take care of
it.
$ cat z.c && gcc -O2 -S -Wall z.c
const char* const a[32] = { "1", "12", "123" };
char d[4];
void f (int i)
{
__builtin_sprintf (d, "%s", a[i]);
}
z.c: In function ‘f’:
z.c:7:26: warning: ‘%s’ directive writing up to 255 bytes into a region of size
4 [-Wformat-overflow=]
__builtin_sprintf (d, "%s", a[i]);
^~
