--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
You can make this valid (maybe not runtime defined) GNU C code that ICEs in=
 the
same way:
```
struct obj {
  int n;
  int l;
};
int main() {
  (struct obj *)((char *)(__SIZE_TYPE__)({ 0; }) - (char *)&((struct obj
*)0)->l);
}

```=
