Description Claudio Saavedra 2023-11-16 07:28:57 PST 
Debugging a CheckedPtr crash by enabling CHECKED_POINTER_DEBUG prints a list of stacktraces for the dangling references of a CheckedPtr, but for some reason the number of stacktraces doesn't match the amount of reference leaks. In the bug I am debugging, m_count is 1, but there are 9 stacktraces. That makes debugging CheckedPtr tricky, as I am not sure which of those is the one that is really leaked.
