--- Comment #1 from ag0aep6g at gmail.com ---
This is a bug in the GC profiler. The array is not relocated. You can check by
comparing the pointers:

----
void main()
{
    int[] arr;
    arr.length = 7;
    int* p = arr.ptr;
    arr.length = 6;
    assert(arr.ptr == p); /* passes */
}
----

I'm changing the title of this issue accordingly.
