Library cross load issue

using ci 3.1.10

foo_library.php

PHP Code:

public function __construct() {
$ci =$ get_instance();
$ci->load->library('bar_library');
} 


bar_library.php

PHP Code:

public function __construct() {
$ci =$ get_instance();
$ci->load->library('foo_library');
} 


no problem in 3.1.6

but 3.1.10, infinity load library.

@resuki,

Instead of...

$ci =$ get_instance();

You should have...

$CI =& get_instance();
