    Summary: Use-after-free when cloning a partially consumed `Vec` iterator

    Details: The `IntoIter` `Clone` implementation clones the whole underlying `Vec`. If the iterator is partially consumed the consumed items will be copied, thus creating a use-after-free access. A proof of concept is available in the original bug report.
