Summary
'merge_sort::merge()' crashes with double-free for `T: Drop`
Details

In the affected versions of this crate, merge_sort::merge() wildly duplicates and drops ownership of T without guarding against double-free. Due to such implementation, simply invoking merge_sort::merge() on Vec<T: Drop> can cause double free bugs.
