segmentation fault when using igbinary

[kn007]

I'm sorry I can't dump the core dump file, because my kernel does not support that.

Test in:
PHP 7.0.1
libmemcached 1.0.18
Memcached 1.4.25(unix socket)
igbinary/igbinary7
php-memcached php7 branch

When i test in php7 code like this,it's work:

$key='test';
$mc=new Memcached();
$mc->addServer('/tmp/memcached.sock', 0);
$mc->set($key,'1234567890',86400);
$data=$mc->get($key);
echo $data;

But when using Wordpress 4.4 with Memcached Object Cache, segmentation fault.

using:

./configure --with-php-config=/usr/local/php7/bin/php-config --enable-memcached-igbinary --with-libmemcached-dir=/usr/local/libmemcached --enable-memcached --disable-memcached-sasl --with-zlib-dir=/usr/local/zlib

it's working, but

PHP Warning:  Memcached::get(): could not unserialize value, no igbinary support in /var/www/kn007.net/wp-content/object-cache.php on line 1300

I'm not sure that it's php-memcached error or igbinary error.

Thank you.
