Description:
Generating the recent changes page on PHP 5.0.3RC1 (problem also occurred on
5.0.1 before upgrading) generates errors of the form:

Fatal error: Only variables can be passed by reference in
/path/to/wiki/includes/ChangesList.php on line 494

It appears that makeKnownLinkObj accepts a reference as its first argument
(&$nt) but lines 494, 495 and 503 of ChangesList.php pass in $rc->getTitle()
which is not a variable.

Possible ways to fix:

• Change makeKnownLinkObj to not use an explicit reference. PHP 5 will pass by

reference automatically but this would cause PHP4 to make a copy of the object.
This inconsistency may preclude this as a solution.

• Assign $rc->getTitle() to a local variable and pass this instead.

PHP5 Workaround: Setting the zend.ze1_compatibility_mode flag emulates much of
PHP4's object behavior and thus no error is emitted.
