issue description
After joomla update from joomla 3.6.0 to 3.6.2, administator login does not work anymore.
Following error is shown after clickin the login button.
Warning: ini_set(): A session is active. You cannot change the session module's ini settings at this time in /var/www/joomla/libraries/joomla/session/storage/memcached.php on line 66
I have versioned the installation in git. when going back to 3.6.0, I can login again. After login I can reinstall the files from 3.6.2 with git and remain logged in, but relogin is not possible.

Systeminfo is saved after login with 3.6.0 and then updating the files.
No difference except version and status numbers between working and broken systeminfo.
Additional comments
Same issue is reported in the forum: http://forum.joomla.org/viewtopic.php?f=709&t=933322
The memcached.php file has not changed between the two versions.
php-memcached is packaged for debian/ubuntu and it is working correctly with joomla 3.6.0 only after update to 3.6.2 it is broken. where's the difference?
It might be packaged for debian but as seen in the links it is not supported
It works in 3.6.2 with session_handler memcache and cache_handler memcached

was not a permanent solution. now session_handler is set to 'none'
Memcached does not work with php 7. Don't try to use it.
joomla system page_cache plugin is working well with php7 and memcached.
global joomla caching in configuration.php is set to 0, but page_cache plugin is enabled. this is the fastest configuration for our huge page.
The same error i faced with memcache 3.0.9-dev . But after search i saw that php7 with memcache and memcached has not full support
Memcached as cache storage works on php7.
Memcached as session storage may have problem as mentioned above.

I am closing this at this time as there is nothing we can do about the external library
