Package: php-memcached
Version: 3.0.1+2.2.0-1
Severity: normal

Dear Maintainer,

Basic configuration for memcached session works without problems:

  session.save_handler = memcached
  session.save_path = "localhost:11211"

But turning on persistent connections breaks this module:

  memcached.sess_persistent = On

First request using the session works fine. The second request
fails and segfault appears in error.log:

  [Sat Aug 05 19:21:28.163528 2017] [core:notice] [pid 641] AH00052: child pid 
656 exit signal Segmentation fault (11)

All further requests hang and fail after a timeout in session_start:

  [Sat Aug 05 19:21:37.774277 2017] [:error] [pid 657] [client ::1:56634] PHP 
Warning:  session_start(): Unable to clear session lock record in 
/var/www/html/session.php on line 7
