    Summary: insert_slice_clone can double drop if Clone panics.

    Details: Affected versions of this crate used `ptr::copy` when inserting into the middle of a `Vec`. When ownership was temporarily duplicated during this copy, it calls the clone method of a user provided element. This issue can result in an element being double-freed if the clone call panics. Commit `20cb73d` fixed this issue by adding a `set_len(0)` call before operating on the vector to avoid dropping the elements during a panic.
