Description:
------------
FreeBSD 7.3 compiled as adm64.
libmemcached-0.40 (from /usr/ports)
libxml2-2.7.7 (from /usr/ports patched and not patched)
PHP-5.2.13 (from source code)
trying memcached-1.0.0, memcached-1.0.1 and memcached-1.0.2 (from source code and from /usr/ports)

PHP ./configure
'--prefix=/usr/local/php-5.2.13' '--target=i686-pc-freebsd'
'--disable-debug' '--enable-exif' '--enable-libxml' '--enable-soap'
'--with-iconv' '--with-zlib' '--enable-cli' '--with-curl'
'--enable-mbstring=all' '--with-gettext'
'--with-apxs2=/usr/local/apache/bin/apxs' '--with-gd' '--with-openssl'
'--with-freetype-dir=/home/www' '--with-jpeg-dir'
'--with-pear=/usr/local/php/lib/php' '--with-freetype-dir=/home/www/'
'--with-mysql=/usr/local/mysql' '--with-mssql' '--with-mcrypt'

PHP modules via extension in php.ini:
extension=pdf.so
extension=rst_sql.so
extension=gpassmode.so
extension=pdo_mysql.so
extension=fileinfo.so
extension=rc4.so

installing memcached.so via /usr/ports (as a module for PHP 5.3.2) - OK
installing memcached.so from source code (source from pecl.php.net, phpize) - OK

When added in php.ini:
extension=memcached.so
then run `php -m', PHP is dumping core "Segmentation fault: 11 (core dumped)"


dmesg: pid 54936 (php), uid 0: exited on signal 11 (core dumped)



Reproduce code:
---------------
in php.ini:
extension=memcached.so

Expected result:
----------------
in shell:
[ root@fbsd73 ~]# php -m
