[2.0.x] Model Cache

[sergeyklay]

Hi!

It seems Model Cache with \Phalcon\Cache\Backend\Memory is broken.

How to reproduce:

1. Install new Phalcon from 2.0.x branch (sha 1dd968e).
2. Clone simple Cli App (I created it right now for this issue)
3. Import to db test data: schema.sql
4. Configure your db connection in services.php
5. Run from terminal ./run

After Robot: 24 I always see Segmentation fault (core dumped).

You can change models cache from \Phalcon\Cache\Backend\Memory to \Phalcon\Cache\Backend\Memcache in service.php. In this case all works fine.

I not tested other adapters, only Memory and Memcache.

Could you submit a full backtrace on a debug build?

[sergeyklay]

@patrick-zippenfenig Unfortunately I don't know how to get dumps files and where they is located for php-cli

[patrick-zippenfenig]

@sergeyklay Example backtrace from cli:

$ gdb --args /usr/bin/php /home/vagrant/.phpstorm_helpers/phpunit.php --configuration /var/www/tests/phpunit.xml
(gdb) run
(gdb) bt ful

output ommited
