A reference counted resource, once represented as a naked pointer and later refactored into a smart pointer, is freed a second time after its refcount has already reached 0, and cleanup then accesses its invalid members.","solution":"Patched in GitHub commit 5ecec9c6fbdbc6be03295685190a45e7eee726ab.
