    Summary: Multiple soundness issues in cgc

    Details: Affected versions of this crate have the following issues: 1. `Ptr` implements `Send` and `Sync` for all types, this can lead to data races by sending non-thread safe types across threads. 2. `Ptr::get` violates mutable alias rules by returning multiple mutable references to the same object. 3. `Ptr::write` uses non-atomic writes to the underlying pointer. This means that when used across threads it can lead to data races.
