Description:
------------
After adding the pspell extension, I'm getting a Segmention fault when running scripts on the command line (CLI). 
However, PHP is running fine through Apache.

The same problem occured on previous php/zend versions:
ZendOptimizer-2.5.10a / php-4.4.2

Upgrading to recent versions (php-4.4.4/ZendOptimizer-3.2.0) didn't solve the problem.

The only way to get rid of the segmention fault right now, is to deinstall the pspell extension.

Reproduce code:
---------------
php -v




Actual result:
--------------

Do not file bugs when you have Zend extensions (zend_extension=)
loaded. Examples are Zend Optimizer, Zend Debugger, Turck MM Cache,
APC, Xdebug and ionCube loader.  These extensions often modify engine
behavior which is not related to PHP itself.

Crash definitely seems to happen in the optimizer...

It seems like this problem is only FreeBSD related. It can be fixed by moving pspell.so to the end of the extensions.ini list.
