Strict warning: Only variables should be passed by reference in nodereference_count_get_fields_db() (line 186 of D:\xampp\htdocs

I received this error message.

FWIW, the error goes away if I replace this line at line 186:

    $table = array_pop(array_keys($db_info));

With these lines:

    $temp = array_keys($db_info);
    $table = array_pop($temp);
