PHP Bug Type: Zend Engine 2 problem
Bug description: Calling exit() from a destructor breaks next executed script
Description:
------------
When a destructor runs and you call exit() from within it, this will break
the next executed PHP script with a "Cannot redeclare..." message. The bug
appears when the script is run on a web server, not from the command line.
I think that the HTTP request must be 1.1 not 1.0, because for me it
appears only when HTTP request has keepalive connection enabled. To
reproduce the bug, place the following script on a web server and run it
from the web browser (in my case it was Internet Explorer 6.0)
Reproduce code:
---------------
<?
class someclass
{
public function __destruct ()
{
exit ("Here we terminate");
}
}
header ("Location: http://"; . $_SERVER ["SERVER_NAME"] . $_SERVER
["SCRIPT_NAME"]);
$obj = new someclass;
function evil ()
{
}
?>
Expected result:
----------------
No output is expected. The HTTP request should loop in redirection calls.
Actual result:
--------------
Fatal error: Cannot redeclare evil() (previously declared in :15) in
/usr/local/apache/site/htdocs/bug.php on line 15
