Comment (by jeff@…):

 I'll dig into it a little bit.

 We probably need to get an additional unit test into the mix that tests
 objects & arrays that refer to an object by directly and by reference.
 These were the original data structures that brought the defect (PHP fatal
 error) to light.

 I am also a little concerned that fixing the defect opens up an infinite
 recursion issue, although that was probably already present in the 4.3 and
 earlier implementations.
