Not entirely sure whats going on:

    vagrant@mediawiki-vagrant:/vagrant/mediawiki$ phpsh
    Loading ctags (in background)
    Starting php
    phpsh failed to initialize PHP.
    Fix the problem and hit enter to reload or ctrl-C to quit.

    Fatal error: request has exceeded memory limit in /vagrant/mediawiki/includes/DefaultSettings.php on line 7099

But there doesn't seem to be a memory limit set:

    vagrant@mediawiki-vagrant:/vagrant/mediawiki$ readlink -f $(which php)
    /usr/bin/hhvm
    vagrant@mediawiki-vagrant:/vagrant/mediawiki$ php -r 'var_dump(ini_get("memory_limit"));'
    string(19) "9223372036854775807"

This is on a freshly destroyed and recreated vagrant instance
