An issue was discovered in the arr crate through 2020-08-25 for Rust. Uninitialized memory is dropped by Array::new_from_template.

`arr` crate contains multiple security issues. Specifically, 1. It incorrectly implements Sync/Send bounds, which allows to smuggle non-Sync/Send types across the thread boundary. 2. `Index` and `IndexMut` implementation does not check the array bound. 3. `Array::new_from_template()` drops uninitialized memory.
