QDeclarativeCompiledBindingsPrivate: There is a memory leak here when QML AnchorChanges is used

QDeclarativeCompiledBindingsPrivate: There is a memory leak here when QML AnchorChanges is used. With the attached example it will never get the reference count of the QDeclarativeCompiledBindingsPrivate down to 0 and therefore it is never deleted. Valgrind didn't show up a problem from what I could see, but on Mac you can see if you instrument the example.
