Description:
------------
I have PHP 7 compiled with litespeed SAPI support. Binary works as expected while used with webserver, but acts weird while invoked from console. That bug was introduced in 7.0.0 release and wasn't present in RC8.

First of all I tested if __DIR__ implementation is consistent between all PHP versions: https://3v4l.org/1lRa2 - yup, it is.
Next I created file inside app catalog named test.php. Than I invoked it from outside of the app directory:

root@server:/home/[redacted]# php app/test.php
string(19) "/home/[redacted]/app"
root@server:/home/[redacted]# php7 app/test.php
string(23) "/home/[redacted]/app/app"

# php --version

# php7 -v

PHP also thinks files are located elsewhere:
require_once(/home/[redacted]/app/app/bootstrap.php.cache): failed to open stream: No such file or directory in /home/[redacted]/app/app/console on line 10


RC8 looks correct though:
# php7 test/test.php
string(10) "/home/test"
# php7 --version
PHP 7.0.0RC8 (cli) (built: Dec  2 2015 14:03:35) ( NTS )

I also spot one difference which may be relevant - running binary from console final version identifies SAPI as "litespeed" while RC8 reports "cli".


Configuration
------------- 
Configuration is identical on both servers.
