PHP 4.4 Breaks Backwards Compatibility

We slightly broke BC for PHP 5 in order to get the reference stuff
resolved. Now I remember (senile me) one of the reasons we didn't apply
this fix to PHP 4.
I suggest to hold the PHP 4.4 release until we see if/what can be done
regarding the BC break. The problem is that this change was made, because
we had to fix behavior which wasn't supposed to work in the first place and
led to corruption.

Hmm, this never worked...so we're not breaking any BC. See bug #20953.

I don't have time until Momday to run 4.3 and 4.4 with that code (bug #20953)
Besides the warning will the result (even if bogus) be the same for both
versions?
