Subject: Re: [PHP-DEV] return NULL by reference
From: jeff@opendbms.com ("Jeffrey Moss")

Well I can't reliably reproduce it, is this expected behavior or not? If
there is a cleaner solution I'd like to try that first.

I'd like to turn off this error altogether even if I have to patch and
recompile. I can't see anything like this in the changelogs. Since when
should anything not be allowed to return null?
