Call-time pass-by-reference deprecation warning

Line 78 has a php warning:
/sites/all/modules/util/util.module on line 78
[15-Aug-2007 15:47:44] PHP Warning: Call-time pass-by-reference has been deprecated; If you would like to pass it by reference, modify the declaration of [runtime function name](). If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file.

Line 78 is:
76 function util_form_alter($form_id, &$form) {
77 if (isset($form['validation_modules'])) {
78 system_modules_util_form_alter($form_id, &$form);
}

Is this something that needs to be patched?
