Description:
------------
Reproduced in php 5.2.6 and php 5.1.6.

funcall module tries to use PZVAL_UNLOCK_FREE which is not available. It is "static inline" defined in zend_execute.c.

Reproduce code:
---------------
<?php
dl("funcall.so");

Expected result:
----------------
Module is loaded fine.

Actual result:
--------------
PHP Warning:  dl(): Unable to load dynamic library '/usr/lib64/php/modules/funcall.so' - /usr/lib64/php/modules/funcall.so: undefined symbol: PZVAL_UNLOCK_FREE in /test.php on line 2

This bug has been fixed in CVS.

In case this was a documentation problem, the fix will show up at the
end of next Sunday (CET) on pecl.php.net.

In case this was a pecl.php.net website problem, the change will show
up on the website in short time.
 
Thank you for the report, and for helping us make PECL better.

I have removed PZVAL_UNLOCK_FRE calling.It's not in the symbol table of php exe and funcall.so.

But it's weird that this error should not be raised if just dl('funcall.so').

As I know, a undefined symbol err will be raised only if calling that symbol.
