Status: Open
Bug Type: Scripting Engine problem
Operating System: RedHat Linux 7.2
PHP Version: 4.0.6
New Comment:
FYI: I did write a script with require_once() inside a for loop to see if just
repetitively requiring a file would crash it. SquirrelMail uses frames so I also tried
that script running in two frames at once. Both ran without crashing so it's at least
more complicated than that.

Also in 4.1.0. I haven't been able to write a simple script to reproduce the crash.
I've stepped through the code (at least through the 4.0.6 code) and require_once()
works over 300 times (a few times requiring ../src/load_prefs.php) before consistently
crashing at the same point. Aolserver is multithreaded -- could it a thread issue?

Can you try newly release 4.1.0?
And please try to provide small, self-containing reproduceable script.
What does a full backtrace give ? (bt full).
Feedback.
