Description:
------------
The code below was tested on WindowsXP + PHP(5.0.5) + Apache(1.3.33) AND Linux + PHP(5.0.5) + Apache(Apache/2.0.53).In both cases this code leads to crash in Apache.The message is "Segmentation fault ......."
Reproduce code:
---------------
set_error_handler('errorHandler');
$crashApache = new crashApache;
try {
$a = array('test'); $result = array();
foreach($a as $b) {
$result[] = $b; $nullValue = null;
foreach($nullValue as $c) {
$result[] = $c;
}
}
$crashApache->start($result);
}
catch(Exception $e) { echo 'This Exception should be catched'; }
class crashApache {
public $someVar = array();
public function start(&$crashParam) {
$this->someVar = $crashParam;
}
}
function errorHandler($errno, $errstr, $errfile, $errline, $vars) {
throw new Exception('Some Exception');
}
Expected result:
----------------
I expect to see the the message "This Exception should be catched"
Actual result:
--------------
Apache crashes with "segmentation fault" message.
