Status: Feedback
Bug Type: Session related
Operating System: Linux 2.4.17
PHP Version: 4.2.1
New Comment:
I guess I have the same problem:
When storing an object within a session it only works as long as the
session filesize doesn't change. 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'

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.

Nah, it doesn't work either.
It is even worse, now the script crashes the very first time after
calling a session_start() while a session variable is registered.

I have RH73 and the same problems... it occurres with php4.2.0, 4.2.1,
4.2.2, 4.3.0 and with apache1.3.26, 2.0.39.
First the scripts seem to work, after a while of using the script the
browser will say something like Request data from localhost... and I
can wait forever :(
It's directly related to session_start because if I remove the
session_start directive or make a "rm -f /<tmp-dir>/sess*", it will
work again

it seems that php sometimes ignores session.save_path and tries to save
the session in the default path "/tmp".
i've set the path to another temp directory on my windows pc.
"/tmp" exists on my linux pc but not on the windows pc. the script
which uses session_start crashes sometimes on my windows pc (also i've
changed the path).
my php-debugger ALWAYS shows a warning that "/tmp" doesn't exist.
