Bug Type: Bug
Bug description:class a {function __construct(){new a();}} new a(); # - kills
php
Description:
------------
I know it's wrong to try to instantiate a class within it's own
constructor,
yet I thought that I should report the crashing of the php interpreter.
Perhaps this case may expose an area of the interpreter that may cause
other problems.
Here is a sample script.
<?php class a {function __construct(){new a();}} new a(); # - kills php ?>
Here is the message produced (with php 5.3.2):
Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to
allocate 261904 bytes) in M:\workspace\html\directAbrasives\lib\t.php on
line 1
Here is my php version:
PHP 5.3.2 (cli) (built: Mar 3 2010 20:47:01)
Copyright (c) 1997-2010 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies
Running this code on PHP 5.2 didn't generate any message at all.
Also, I tried a catching exceptions, yet it appears that none are thrown in
this case.
I am operating on WindowsXP.
Cheers.

Some kind of error message with a line number saying you can't do this.

--------------
Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to
allocate 261904 bytes) in M:\workspace\html\directAbrasives\lib\t.php on
