An issue was discovered in the simple-slab crate before 0.3.3 for Rust. remove() has an off-by-one error, causing memory leakage and a drop of uninitialized memory.

`Slab::index()` does not perform the boundary checking, which leads to out-of-bound read access. `Slab::remove()` copies an element from an invalid address due to off-by-one error, resulting in memory leakage and uninitialized memory drop.
