When I change some values so that the filesize grows, PHP crashes as soon as I touch another object value. Apache reports: notice] child pid 6571 exit signal Segmentation fault (11) I've got some Example files for you, if you like to reproduce the error: File 1 - object definition: --------------------------- class User { var $valid; var $punkte; function User() { $this->clear_values(); } function clear_values() { $this->valid = false; $this->punkte = 0; } function login() { $this->valid = true; } function logout() { $this->clear_values(); } } file 2: login.php (just the PHP part) ----------------- require("User2.class.php"); $user = new User(); session_register('user'); $user->login(); echo "Status: " . $user->valid; echo "<br>Punkte: " . $user->punkte; file 3: modify -------------- require("User2.class.php"); $user = new User(); session_register('user'); if ($user->valid) $user->punkte++; echo "Status: " . $user->valid; echo "<br>Punkte: " . $user->punkte; file 4: logout -------------- require("User2.class.php"); $user = new User(); session_register('user'); $user->logout(); echo "Status: " . $user->valid; echo "<br>Punkte: " . $user->punkte; for testing: call login.php, then recall modify.php several times until $user->punkte is bigger than 10 then call logout.php -> apache will report that segmentation fault and your session is dead. Any further access to that session will timeout your browser. Other php functions work perfectly! The content of the session file itself is still valid and there is no problem with system rights... my system: Redhat 7.1, kernel 2.4.2-2 Apache 2.0.39 PHP 4.2.1 compile options: ./configure' '--with-mysql' '--with-apxs2=/www/bin/apxs' '--enable-trans-sid' '--enable-sysvsem' '--enable-sysvshm' ------------------------------------------------------------------------ [2002-08-30 04:51:13] derick@php.net Thank you for this bug report. To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. A backtrace would be very nice, it is much easier debugging with it.

It is even worse, now the script crashes the very first time after calling a session_start() while a session variable is registered. ------------------------------------------------------------------------ [2002-08-27 22:17:58] sniper@php.net Please try using this CVS snapshot: http://snaps.php.net/php4-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-latest.zip ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
