--- Comment #8 from Steven Dwy <me at yoplitein.net> ---
Further investigation suggests `__equals` may be to blame:
```
int main()
{
        import std.random; // to defeat constant folding
        auto a = new int[4];
        foreach(ref v; a) v = uniform(0, 10);
        auto b = new int[4];
        foreach(ref v; b) v = uniform(0, 10);
        return cast(int)(a == b);
}
```

This is further supported by debugging a faulty binary, with the debugger
stopping on the first overload of __equals:
