Tested:

```
void main() {

    import std.stdio;


    struct test_struct {
       char[] Txt;
    }

    test_struct[] A;


    A.length = 1;
    A[0].Txt.length = 1;
    A[0].Txt[0] = 'X';

    writeln(A);


    auto B = A.dup;

    writeln(A, B);

    A[0].Txt[0] = 'Y';

    writeln(A, B);
}

```

Got:
```
[test_struct("X")]
[test_struct("X")][test_struct("X")]
[test_struct("Y")][test_struct("Y")]
```

Expected last line to be Y,X not Y,Y.
