Description:
------------
If you throw an exception that doesn't use a number for the error code, a "Fatal Error" message box pops up saying:

Wrong parameter count for exception([string $exception [,long $code]])


This hangs the current server thread until the message box is selected which could be used to lock all of the available threads on the server and effectively take the server offline.


Reproduce code:
---------------
<?php

throw new Exception("Invalid Error Code -->", "ERRO_ASDASD");

?>

Expected result:
----------------
Throw an exception as normal.

Actual result:
--------------
The thread will hang and the page won't load until you close the message popup. It will then display this:


"Fatal error: Wrong parameter count for exception([string $exception [, long $code ]]) in Unknown on line 0"

Hi there,

I have now installed the latest PHP 5 and Apache 1.3.33 on a clean machine. Whilst the initial problem seems to have gone away the Apache web server now crashes but I believe it's still a problem of PHP because debug log mentions php5ts.dll saying the following:

szAppName: Apache.exe
szAppVer: 0.0.0.0
szModName: php5ts.dll
szModVer: 5.1.0.0
offset: 00007c9e

An interesting fact that the offset is _allways_ the same. Although it doesn't crash every time you run the example code (from original bug report) holding refresh for a few seconds causes the problem consistantly.

I have saved the memory dump of the program if you need it.
