    Summary: push_cloned can drop uninitialized memory or double free on panic

    Details: Affected versions of `stack_dst` used a `push_inner` function that increased the internal length of the array and then called `val.clone()`. If the `val.clone()` call panics, the stack could drop an already dropped element or drop uninitialized memory. This issue was fixed in `2a4d538` by increasing the length of the array after elements are cloned.
