Summary

The `ApplyResult` type contains a raw pointer to a C++ memory object and has a derived `Clone` implementation which creates a reference to this object without incrementing the associated reference counter.

As a result, if an instance of `ApplyResult` is duplicated through `Clone` and both instances are dropped a use-after-free can occur.
