Description:
------------
I got unexpected PHP crashes when unserializing a object. There is no recursiveness in the serialized object as the data is created from a JSON object.

However, when you disable the recursive ArrayObject creation, the script succeeds. Also, when creating a recursive stdClass(), the problem doesn't exist

Test script:
---------------
Error unserializing with ArrayObject:
https://3v4l.org/hbSRC

This succeeds with the stdClass:
https://3v4l.org/HNXR6

Expected result:
----------------
Valid unserializing
