Codeigniter 2.1.4 and php5.6

[eluser]DougW[/eluser]
I am getting the following error with php 5.6 and CI 2.1.4


A PHP Error was encountered

Severity: Notice

Message: Only variable references should be returned by reference

Filename: core/Common.php

Line Number: 257

I have seen this reported before but this is a new installation. Is it OK just to remove the & from line 257 in Common.php? Is there a better fix besides turning off notices in php?
