From: miha dot space at gmail dot com Operating system: Windows 7, Linux openSuse 11.2 PHP version: 5.3.1 PHP Bug Type: *Programming Data Structures Bug description: LinkedList max nodes, Segmentation fault 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 bug report at http://bugs.php.net/?id=51132&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=51132&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=51132&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=51132&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=51132&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=51132&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=51132&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=51132&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=51132&r=needscript Try newer version: http://bugs.php.net/fix.php?id=51132&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=51132&r=support Expected behavior: http://bugs.php.net/fix.php?id=51132&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=51132&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=51132&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=51132&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=51132&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=51132&r=dst IIS Stability: http://bugs.php.net/fix.php?id=51132&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=51132&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=51132&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=51132&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=51132&r=mysqlcfg
