Symfony version(s) affected: 4.4.0

Description
When I run my behat tests, I end up getting a Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 32768 bytes) in /var/www/project/var/cache/test/pools/AqNbLoad6z/E/7/9TL8Zv8iSmZZttWPui9Q on line 1 after several scenarii

How to reproduce
This occurs every time I try to run the full behat tests suite

Possible Solution
Maybe a container reload issue ?

Additional context

• This worked flawlessly with symfony version 4.3.x
• I use the symfony/http-kernel 4.4.x-dev
• I updated my Kernel with $container->setParameter('container.dumper.inline_factories', true);
