Description:
------------
php以debug模式编译。如果没有释放zval*，dl加载模块的时候会引起段错误。

I compiled php in debug mode.If the zval* isn't freed,the php will cause a 
Segmentation fault when load the module using dl();



Test script:
---------------
In PHP:
<?php
test_call();
echo "The Programe is over~\n";
?>


Expected result:
----------------
printf the detail info abount Memory leak

Actual result:
--------------
There is the same error with php 5.3.8.
