PHP Fatal error: Cannot redeclare recurse()

After plugin update (not sure from what version) I’ve got this in error log:
PHP Fatal error: Cannot redeclare recurse() (previously declared in wp-content/plugins/addthis/addthis_settings_functions.php:476) in wp-content/plugins/addthis/addthis_settings_functions.php on line 476

<br />
if (!function_exists('array_replace_recursive')) {<br />
  function array_replace_recursive($array, $array1) {<br />
    function recurse($array, $array1) {<br />
...<br />

Seems like array_replace_recursive() calls more than once and it causes redeclaration of recurse() function.

I don’t call it in template or anywhere in code. Just set it up in admin panel.

Could you help me with it?
Thank you.
