struct Widget {
   private int[] array;
   this(uint length) {
      array = new int[length];
   }
   this(this) {
      array = array.dup;
   }
}

void main() {
    auto a = new Widget[1];
    a[0] = Widget(10);
    auto b = a.dup;
    assert(b[0].array !is a[0].array);
}

The code fails. It should pass.
