 Call-time pass-by-reference is deprecated in PHP 5.3, but actually is
 deprecated in many hosts prior to PHP 5.3, who setting
 allow_call_time_pass_reference to false. The PHP developers recommend that
 all developers move away from this usage pattern (see
 http://php.net/manual/en/ini.core.php, under

 I've attached a patch for bp-groups-classes.php. There are many other
 parts of BP where this occurs. To fix each occurrence, however, we need to
 first verify that removing the pass-by-reference wouldn't have undesirable
 side effects (i.e. prevent a required modification to a variable). So far,
 however, it looks like many of the pass-by-references don't actually
 modify the passed variables.

 If you're open to it, I can work on this some more.

 As a related issue I would recommend turning on WP_DEBUG and noting the
 other notices. Each notice in PHP incurs a performance cost even if it
 isn't logged.
