You aren't understanding what that flag does:
<php.ini>
; - allow_call_time_pass_reference = Off [Code cleanliness]
; It's not possible to decide to force a variable to be passed by reference
; when calling a function. The PHP 4 style to do this is by making the
; function require the relevant argument by reference.
</php.ini>
This flag does not apply to what you have above. What this disables
is the ablity to decide at 'call time', of the function, to pass by
reference or not. This was an old method and changed in php 4:
function foo($bar) { }
foo(&$mybar); // this is what it doesn't allow.
It is up to the function to declare if you want to pass by
reference or not, this is not depricated:
function foo_reference(&$bar) { }
function foo_copy($bar) { }
