    Summary: insert_many can drop elements twice on panic

    Details: Affected versions of `insert_many` used `ptr::copy` to move over items in a vector to make space before inserting, duplicating their ownership. It then iterated over a provided `Iterator` to insert the new items. If the iterator's `.next()` method panics then the vector would drop the same elements twice.
