Operating system: Linux (mandrake 10)
PHP version: 5.0.1
PHP Bug Type: Zend Engine 2 problem
Bug description: Segmentation fault with not catched exception
Description:
------------
[ bad english, i know ]
It seems that PHP 5 is not very stable.
My code segfaults every 3-4 days :'(
Reproduce code:
---------------
<?php
class B {
}
class A {
public $b;
public function __construct() {
$this->b = new B;
}
public function build() {
return $this->b;
}
}
class C {
private $b;
public function __construct() {
$a = new A();
$this->b = $a->build();
try {
throw new Exception;
} catch(Exception $e) {
}
}
public function __destruct() {
throw new Exception;
}
}
$C = new C;
?>
Expected result:
----------------
Something like "An uncaught exception has been thrown..."
Note that the code works as expected if you remove the following lines :
"$a = new A();
$this->b = $a->build();"
Actual result:
--------------
segmentation fault :)
