 // CHECK-LABEL: define {{.*}} @{{.*}}test_one{{.*}}(
----------------
I would expect to see here:

```
struct Zero {
  int a[0];
};

// CHECK-LABEL: define {{.*}} @{{.*}}test_zero{{.*}}(
int test_one(struct One *p, int i) {
  // CHECK-STRICT-0-NOT: @__ubsan
  // CHECK-STRICT-1-NOT: @__ubsan
  // CHECK-STRICT-2-NOT: @__ubsan
  // CHECK-STRICT-3:     call void @__ubsan_handle_out_of_bounds_abort(
  return p->a[i] + (p->a)[i];
}
```
