Description:
------------
Try it on Freebsd 6.1, 6.2 i386, Freebsd-7.0-amd64
From ports with freebsd related patches and without. 
I try php-5.2.5 and php5.2-dev snap 11Feb2008.
ZendOptimizer-3.3.0a-freebsd6.0-i386 (amd64).
php-cgi crashes and write core
Program terminated with signal 11, Segmentation fault.

---------------
$ ./configure --with-layout=GNU --with-config-file-scan-dir=/usr/local/etc/php --disable-all --enable-libxml --with-libxml-dir=/usr/local --enable-reflectio
n --program-prefix= --enable-fastcgi --with-regex=php --with-zend-vm=CALL --enable-zend-multibyte --disable-ipv6 --prefix=/usr/local --mandir=/
usr/local/man --infodir=/usr/local/info/ i386-portbld-freebsd6.2

$ cat php.ini
