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.
