Segmentation fault: 11 (core dumped)

In php.ini:

zend_extension_manager.optimizer=/home/support/akriventsov-sp/ZendOptimizer-3.3.0a-freebsd6.0-i386/data/
zend_optimizer.version=3.3.0a
zend_extension=/home/support/akriventsov-sp/ZendOptimizer-3.3.0a-freebsd6.0-i386/data/ZendExtensionManager.so

I have the same in freebsd 6.2, 6.3 with php-5.2.5,5.2.5,5.2.6RC4 with different versions of zend 3.2.6 and 3.3.0a

cd php-5.2.5
./configure
make
install zend optimizer to php.ini
sapi/cgi/php-cgi -c /path/to/php.ini -m
