codeigniter 1.7 on PHP5.3

[eluser]Gustav[/eluser]
More errors when migrating from PHP v5.2.3 to v5.3.0:

Deprecated: Assigning the return value of new by reference is deprecated in system\codeigniter\Common.php on line 130

Deprecated: Assigning the return value of new by reference is deprecated in system\codeigniter\Common.php on line 136

Code:

// File Common.php in system\codeigniter\
// Lines from 127 to 137

if ($is_subclass == TRUE)
{
    $name = config_item('subclass_prefix').$class;
    $objects[$class] =& new $name(); // line 130
    return $objects[$class];
}

$name = ($class != 'Controller') ? 'CI_'.$class : $class;

$objects[$class] =& new $name(); // line 136
return $objects[$class];

And not only in that file.

v5.3.0 is big problem for CI 1.7.1 because all my CI projects throw errors.
CI needs an update.
