An issue was discovered in the algorithmica crate through 2021-03-07 for Rust. In the affected versions of this crate, mergesort::merge() wildly duplicates and drops ownership of T without guarding against double-free. Due to such implementation, simply invoking mergesort::merge() on Vec can cause double free bugs.
