--- Comment #12 from Richard Cattermole <alphaglosined at gmail.com> ---
Another example that can trigger this (in -betterC):

```d
extern(C) void main() {
    wchar[2] got;
    func(got);
}

void func(out wchar[2] v) {
}
```

Why do these hooks even exist? They could be a simple rewrite to a foreach loop
in the compiler and not depend on the runtime at all, let alone functions in
rt.
