Memcache module conflict with APC 3.1.8 ? [#1147672]

APC 3.1.8 just released a few days ago and today, I upgraded from version 3.1.7 to 3.1.8. After upgraded, I always got blank page / Internal Server Error. (Depends on Browser) Tested it with Nginx 1.0.0, Apache 2.2, PHP 5.3.6 (PHP-FPM), MySQL 5.5, Memcached 1.4.5 with PECL Memcached extention (Tried both 1.0.2 / 2.0 Beta). This problem appear only on Drupal site. SMF Forum is working fine.

My config in Drupal is :

$conf = array(
'cache_inc' => './sites/all/modules/memcache/memcache.inc',
'session_inc' => './sites/all/modules/memcache/memcache-session.inc',
'memcache_key_prefix' => 'test',
);

$conf['memcache_options'] = array(
Memcached::OPT_COMPRESSION => FALSE,
Memcached::OPT_DISTRIBUTION => Memcached::DISTRIBUTION_CONSISTENT,
Memcached::OPT_BINARY_PROTOCOL => TRUE,
);

Once I took this line out -> 'cache_inc' => './sites/all/modules/memcache/memcache.inc', It came back to work normally.

So, I just downgraded back to 3.1.7. and everything works ok as it used to be. Now, I don't know it's a bug in APC or Memcache Drupal module.
