I was able to simplify the code to following test code which is far from our real application, but causes crash in the same kind of code construction: echo is_null($form) ? '': $form; I am able to reproduce this crash with PHP 5.3.3 and PHP 5.2.14. It does not crash when runnig in CLI mode. How to run: 1. configure include path to contain Zend library (I was testing with http://framework.zend.com/svn/framework/standard/tags/release-1.10.6/library/Zend) 2. restart apache 3. point your browser to bug.php Test script: --------------- set_include_path('.' . PATH_SEPARATOR . '/var/www/library'); require 'Zend/Form.php'; class TestClass { function crash() { $form = new Zend_Form(); echo is_null($form) ? '': $form; // it works if there echo instead of die() here die("this ends with signal 11 SIGSEGV, returns HTTP code 500"); } } $test = new TestClass(); $test->crash(); Expected result: ---------------- the program should die and print out message "this ends with signal 11 SIGSEGV, returns HTTP code 500" Actual result: -------------- HTTP response code 500 returned and signal 11 SIGSEGV logged ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52565&edit=1
