See my two testcases: http://files.derickrethans.nl/patches/reference-bug.phps http://files.derickrethans.nl/patches/reference-test-case2.phps But you would only spot it with valgrind and turning off Zend's memory manager. The MM hides this kinds of errors pretty well. > I'm reading the mailing list throught the NNTP interface and it seems to miss > part of the conversation as the thread starts with Re: References Problem > Patch.

As I tried to do that in our large code base, I would say that's totally not possible to do. There is no way you know you're doing someting wrong, as there are no warnings and go through 200k+ lines of code without missing an instance is impossible. regards, Derick -- Derick Rethans http://derickrethans.nl | http://ez.no | http://xdebug.org
