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 Starting program: /usr/sbin/apache2 -X -D PHP5 -D SSL [New Thread 16384 (LWP 21590)] Detaching after fork from child process 21596.
