This indicates a bug in the program. This Undefined Behavior check is optional, and cannot be relied on for safety.Arcs backed by a static should never reach a strong count of 0. Likely decrement_strong_count or from_raw were called too many times.Arc/Weaks backed by a static should never be deallocated. Likely decrement_strong_count or from_raw were called too many times.
