Description:
------------
Abstract:
-------------------
PHP 4.4.0 shows a "Notice: Only variable references should be returned
by reference in ..." Notice when it shouldn't.
The bug can only be reproduced with PHP 4.4.0. And it can only be
reproduced on a few systems, on most it returns the expected result
(all test platforms had error_reporting(E_ALL);).
Furthermore, code that seems to be equivalent doesn't result in a
Notice. And two different systems with almost the same setup don't show
the same results.
I couldn't isolate the bug further than this. Maybe it's a compile
options issue, maybe it has to do with the scope of variables, I don't
know.

Disclaimer:
-------------------
You may think this is another bogus bug report for the
return-by-reference / assign-by-reference / pass-by-reference Notices
in PHP 4.4.0.

But I'm quite sure it isn't. I've patched our framework and wrote some
recommendations on how to code the right way:

. But you don't need to follow this link. I just want to point out that
this is a real issue.

Details:
-------------------
Please take a look at the reproduce script.
