New Comment:
This is expected behaviour. You *need* the $a =& func(),
a mere function &func() definition is not sufficient.
Agreed, this is not really nice... But $a = func() should
always return by value, you don't need to know how func() is
defined.
Equally, $a =& func() shouldn't work when it isn't defined
as returning by reference, since the function might not be
expecting it.
Btw: This has nothing to with call_time_pass_ref

let's run this code
<?php
class A{
function &b(&$f) {
$d=&$f;
$f='5';
return $d;
}
}
$c='3';
$d=new A();
$h=$d->b($c);
//$h=&$d->b($c); //The & is needed to work well
//we get $h=&$c;
$h='9';
echo $c. ' '.$h;
//since we should see 9 9, but we can see 5 9
?>
we get 5 9
If we adapt the code to:
//$h=$d->b($c);
$h=&$d->b($c); //The & is needed to work well
we get 9 9, and that should be the good value, rigth?

Works for me. What are the results in your case?

I tried it with: allow_call_time_pass_reference = Off and allow_call_time_pass_reference = On
It seems that the result is not send automatically as a reference
class A{
function &b(&$f) {
$d=&$f;
$f='5';
return $d;
}
}
$c='3';
$d=new A();
$h=$d->b($c);
$h=&$d->b($c); //The & is needed to work well
$h='9';
echo $c. ' '.$h;
The value of c is not updated correctly if we don't ask for a reference
