    Summary: move_elements can double-free objects on panic

    Details: Affected versions of `scratchpad` used `ptr::read` to read elements while calling a user provided function `f` on them. Since the pointer read duplicates ownership, a panic inside the user provided `f` function could cause a double free when unwinding. The flaw was fixed in commit `891561bea` by removing the unsafe block and using a plain iterator.
