--- Comment #9 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced testcase:
extern __inline
__attribute__ ((__gnu_inline__))
int
sprintf (char *__restrict __s, const char *__restrict __fmt, ...) {
return __builtin___sprintf_chk (__s, 2 - 1, __builtin_object_size (__s, 2 > 1),
__fmt, __builtin_va_arg_pack ());
}
void cap_to_text(int cmb)
{
char buf[(23 * ((2) * 32))+100];
char *p;
int n, t;
p = 20 + buf;
for (t = 8; t--; )
{
for (n = 0; n < cmb; n++)
p += sprintf(p, "a,");
p--;
sprintf(p, "+");
}
}
When p-- happens, it will always be buf+somesmallvalue.
