--- Comment #15 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
A minimal reproducer:
$ cat t3.c
extern int printf (const char *__restrict __format, ...);
void test (void)
{
printf
("%llu01233456789012334567890123345678901233456789012334567890123345678901233456789012334567890123345678901233456789012334567890123345678901233456789");
}
$ ./xgcc -B. -c t3.c -Wformat
t3.c: In function ‘test’:
