Edit report at http://bugs.php.net/bug.php?id=51187&edit=1 ID: 51187 Updated by: aharvey@php.net Reported by: bostjan at a2o dot si Summary: Segmentation fault with Zend_Form/Zend_View -Status: Open +Status: Feedback Type: Bug Package: Reproducible crash Operating System: Linux PHP Version: Irrelevant New Comment: You can find instructions on generating a backtrace at http://bugs.php.net/bugs- generating-backtrace.php.

How do I acquire a stack track? ------------------------------------------------------------------------ [2010-03-03 00:37:52] johannes@php.net I assume this is an endless recursion, can you please provide a stacktrack? ------------------------------------------------------------------------ [2010-03-03 00:37:51] johannes@php.net -Status: Open +Status: Feedback ------------------------------------------------------------------------ [2010-03-03 00:32:33] bostjan at a2o dot si Description: ------------ If I accidentally pass a wrong parameter to Zend_Form when creating a new element (common mistake during development) and I pass an element itself, it causes segmentation fault. I don't have time to investigate this issue further to pinpoint exact location of segfault in Zend Framework, therefore I am attaching only proof of concept code below, which uses Zend Framework classes. Test script: --------------- // Enable Zend Autoloader require_once "Zend/Loader/Autoloader.php"; $autoloader = Zend_Loader_Autoloader::getInstance(); // Get form object $domain = 'a2o.si'; $Form = _getForm($domain); echo $Form->render(); // Function that creates form object function _getForm ($domain) { $View = new Zend_View(); // Create form $Form = new Zend_Form(); $Form->setView($View); $Form->setAction('/domain/createrr') ->setMethod('post') ->setName('form_createrr'); // Add an element - NOTE A BUGGY WAY TO ADD IT // ($domain is not 'a2o.si' anymore after this line) $domain = $Form->createElement('hidden', 'domain'); $domain->setValue($domain); $Form->addElement($domain); return $Form; } Expected result: ---------------- Form in HTML notation. Actual result: -------------- Segmentation fault (tested with CLI and Apache Handler) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=51187&edit=1
