Ive not been able to reproduce this as it only seems to occur with *VERY* complex objects like my code generates. Some strange facts I've found out about while trying to pinpoint the exact cause: - In some occasions, escaping a foreach on $this->property in an objects __wakeup(); made the problem disappear. - When manually decoding a session file, (about 3M) I also got a segmentation fault. After increasing the available memory to over 64M the session got correctly decoded. With this *SICK* amount of memory, the actual script kept segfaulting, however, it took longer to segfault so expect a memory leak or infinite loop. - This problem occurs on a Fedora Core 2, Apache 2.0, PHP 4.3.10 machine, while on RedHat 7.3, Apache 1.3.29, PHP 4.3.6 everything works fine. So suspect the bugfix (4.3.9->4.3.10) on session handling for spooky behaviour. I will try to keep you all up to date. Thank you, Eric van Blokland Reproduce code: --------------- Contact me for access to code.
