--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
If someone is worried about uninitialized variables or an executed infinite
loop, this also ICEs at -O3:
```
long t;
long a() {
long b = t, c = t;
for (; b < 31; b++)
c <<= 1;
return c;
}
long long t1;
static
int d() {
if (!t1)
return 0;
e:
f:
for (; a();)
;
goto f;
return 0;
}
int main() { d(); }
```
