With recent CVS checkout I got it to crash with this backtrace (same

Description:
------------
When creating a error function which has a parameter with an reference,
php will create an endless loop in calling itself (i think).
The proces keeps running and will not stop.
You can blog up a windows machine running under iis/cgi because it
doesn't react on set_time_limit().
I've seen this problem in php 4.x and 5.x under windows and in linux on
a dual system. Linux with a single cpu seemed not to have this problem
(?)
(I'm using an additional parameter to my error function because of
custom calling of the function)
Reproduce code:
---------------
<?
function
customErrorHandler($fErrNo,$fErrStr,$fErrFile,$fErrLine,&$fClass) {
echo "error :".$fErrStr;
}
set_time_limit(5);
error_reporting(E_ALL);
set_error_handler("customErrorHandler");
define("TEST",2);
//should return a notice that the constant is already defined
define("TEST",3);
?>
Expected result:
----------------
There should be a notice about the redefined "TEST" define
Actual result:
--------------
An endless loop.
