Bug #52565 [NEW]: print out of Zend_Form causing segmentation fault
From:
Operating system: Linux
PHP version: 5.3.3
Package: Reproducible crash
Bug Type: Bug
Bug description:print out of Zend_Form causing segmentation fault
Description:
------------
Our real application is crashing with signal 11. 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
