Description: crash when restoring references to objects
I think this bug is strictly related to bug #8676.
I didn't look close enough to all open bugs wher reporting this one. I'll test new CVS
when #8676 will be closed.

Reclassifying (I don't think it can be reproduced with 'pure scripting' alone, so
it's probably a session module bug

Here are two scripts that operates on referenced objects. make.php creates object $b with reference
to object $a as argument.
After serialize/unserialize show.php checks if the reference still exists.
PHP 4.0.1pl1 lost references.
PHP 4.0.4pl1 segfaults on show.php
PHP 4.0.5 segfaults on show.php and(!) sometimes on make.php
Config line:
./configure --with-pgsql=shared --with-apxs --sysconfdir=/etc --prefix=/usr
--localstatedir =/var --with-config-file-path=/etc/httpd/conf/
--with-gettext=/usr/share/gettext
make.php:
<?
class ClassA {
var $arg_a;
};
class ClassB {
var $arg_b;
function ClassB(&$a) {
$this -> arg_b = &$a;
}
};
session_start();
session_destroy();
session_register("b");
session_register("a");
$a = new ClassA();
$a -> arg_a = 4;
$b = new ClassB($a);
echo "done. Click <a href="show.php">here</a>";
?>
show.php:
<?
class ClassA {
var $arg_a;
};
class ClassB {
var $arg_b;
function ClassB(&$a) {
$this -> arg_b = &$a;
}
};
session_start();
$a -> arg_a = 6;
echo $b -> arg_b -> arg_a;
?>
