The property observer reference used during binding evaluation can become invalidated as the container used to maintain the the observer would invalidate the existing observers during its resize, leading to referring to invalid memory. Recognize that we do not need to store the observer, but only its binding - the observer itself is not used later. Therefore, change the PendingBindingObserverList to become a list of QPropertyBindingPrivatePtr to avoid the issue.
