One more test case for probably same issue:

```D
struct Foo {
    this(ref return scope Foo rhs) {}
    ~this() {}
}

struct Bar {
    @disable this(this);
    Foo[2] foos = void;
}

extern (C)
void main() {}
```

I've tracked this down to this line:
https://github.com/dlang/dmd/blob/a6f49dade85452d61d9ebcf329e2567ecacd5fab/src/dmd/e2ir.d#L2606

So it has something to do with array copy constructor for `foos` array that it
generates either though Bar has disabled copying?

And missing location in error output is not helping at all to figure out where
is the problem :(
