           Summary: Difference between slicing a slice and a reference to
                    a slice
           Product: D
           Version: D2

            Status: NEW

DMD treats these 2 cases differently, while GDC works as expected and LDC is
being fixed accordingly:

```
@safe:

int[] globalArray;

ref int[] getSliceRef() { return globalArray; }

int getLowerBound()
{
    globalArray = [ 666 ];
    return 0;
}

void main()
{
    globalArray = [ 1 ];
    auto r1 = globalArray[getLowerBound() .. $];
    assert(r1 == [ 666 ]);

    globalArray = [ 1 ];
    auto r2 = getSliceRef()[getLowerBound() .. $];
    assert(r2 == [ 1 ]); // BUG, should be [ 666 ]
}
```
