Thanks. ------------------------------------------------------------------------ [2010-02-24 09:16:21] miha dot space at gmail dot com Description: ------------ Is there any limit i also tried with memory_get_usage and with 29000 linkedlistnodes it uses about 9.25MB. In php.ini i have max 128MB, so this can't be the problem. Reproduce code: --------------- <?php class LinkedListNode { public $data; public $next; public function __construct($data) { $this->data = $data; $this->next = NULL; } } class LinkedList { private $first; private $last; public function __construct() { $this->first = NULL; $this->last = NULL; } public function insertLast($data) { $node = new LinkedListNode($data); if( $this->first != NULL ) { $this->last->next = &$node; $this->last = &$node; } else { $this->first = &$node; $this->last = &$node; } } } $list = new LinkedList(); /* it works for($i = 0; $i < 29488; $i++) { $list->insertLast(1); }*/ // Segmentation fault for($i = 0; $i < 29489; $i++) { $list->insertLast(1); } ?> Expected result: ---------------- Nothin, it should exit normally, not segfault. Actual result: -------------- php test2.php Segmentation fault ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=51132&edit=1
