I confirmed the problem, but there is in fact no error messages from
php.

chinese.

Description:
------------
gd (ver 2.0.28) have a danger bug
a error image can pass php's test
but it would make a fatal error
other question:Could you tell me if you deal with bug report in
Chinese?
i'm chinese
my english is very poor
here's the bug report in Chinese:
当有恶意的用户提交一个错误的图像文件
这个文件的文件头是正确的，但主体是错误的，没有结束
提交上去以后，就会引起
php 的致命错误
www 服务会停止
另外问一下：用中文报告会不会处理的？
Reproduce code:
---------------
<?php
$file = 'http://dev.hkrcn.com/testimg.gif';
$im = imagecreatefromgif($file); // here a fatal error
Expected result:
----------------
cause a error,then stop running
Actual result:
--------------
memory-leak
------------------------------------------------------------------------
