Description:
------------
I'm executing this line of code:

$o is a custom COM object
$s = $o->Fields['ICON']->Images[0]->GetResizedUrl(55,55,0);


It works fine in PHP 5.2.0. After installing 5.2.1 it tells me "Cannot pass parameter 1 by reference". Note that no used COM methods/properties use byref parameters.

---------------
I can make it work after any of these work-arounds:

1) $x = o->Fields['ICON']->Images[0];
   $s = $x->GetResizedUrl(55,55,0);

2) $n = 0;
   $s = $o->Fields['ICON']->Images[$n]->GetResizedUrl(55,55,0);

3) $n=55; $n2=0;
   $s = $o->Fields['ICON']->Images[0]->GetResizedUrl($n,$n,$n2);



Reproduce code:
---------------
A custom COM object is involved -> reproduce code is useless

Well, I doubt we can fix something that we can't reproduce.
Are you sure 5.2.0 works fine for you?
What if you take php_com.dll (or whatever it's name) from 5.2.0 and put it instead of the one from 5.2.1?

5.2.0 works fine, I'm sure. There is no php_com.dll or similiar in the ext folder. COM is built-in I think.

The PHP 5.2.2 downloaded on 2006-03-20 works well. Thanks.
