An issue was discovered in the xcb crate through 2021-02-04 for Rust. It has a soundness violation because transmutation to the wrong type can happen after xcb::base::cast_event uses std::mem::transmute to return a reference to an arbitrary type.
The product does not check the return value from a method or function, which can prevent it from detecting unexpected states and conditions.
