Bug #53237 [NEW]: LinkedList max nodes Segmentation fault

From: Operating system: Vista, Linux PHP version: 5.3.3 Package: SPL related Bug Type: Bug Bug description:LinkedList max nodes Segmentation fault Description: ------------ I test linkedList performance and memory usage on Windows Vista Premium with PHP 5.3.3. When list length > 34860 I have server fatal Error ( Segmentation fault) and my fast-cgi script closed. I try test on Linux (PHP 5.2.6) but have some error if length ~ 32735. This error is not related with memory limit. Test script: --------------- class LinkedList { private $_length = 0; private $_head; private $_tail; public function add($data) { $node = (object) array('data' => $data, 'next' => null); if ($this->_length == 0) { $this->_head = $node; $this->_tail = $node; } else { $this->_tail->next = $node; $this->_tail = $node; } $this->_length++; } } $a = new LinkedList(); $startMemory = memory_get_usage(); $start = microtime(true); for ($i = 1; $i <= 34860; $i++) { $a->add($i); } $endMemory = memory_get_usage(); $end = microtime(true); print(($end - $start) . '<br />'); print((int) (($endMemory - $startMemory) / 1024) . '<br />'); Expected result: ---------------- If length = 34860 I got 0.12323784828186 11276 -- Edit bug report at http://bugs.php.net/bug.php?id=53237&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=53237&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=53237&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=53237&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=53237&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=53237&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=53237&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=53237&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=53237&r=needscript Try newer version: http://bugs.php.net/fix.php?id=53237&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=53237&r=support Expected behavior: http://bugs.php.net/fix.php?id=53237&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=53237&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=53237&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=53237&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=53237&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=53237&r=dst IIS Stability: http://bugs.php.net/fix.php?id=53237&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=53237&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=53237&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=53237&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=53237&r=mysqlcfg
