Description:
------------
When trying to initialize one object, I had copy and pasted code for
the factory methods into another object and didn't change the code.
When one object holds a reference to another object, and when the
referenced object returns a copy of the original object when
instantiated, apache 2.0.52 segfaults.
Reproduce code:
---------------
http://www.penguincoder.org/phpnuke.phps
Expected result:
----------------
I had expected a reference to one of my objects which would contain a
reference to a driver for the backend, but instead apache segfaulted.
Nothing was printed to the screen, however the system error_log
detailed that apache had segfaulted.
Actual result:
--------------
(gdb) run -X -D PHP5 -D SSL
