Cloning Laravel4 requests

This problem is driving me crazy.
It looks like cloning the request is not working as expected since the last composer update.
The weird thing is that if I don't execute the ->get()

clone of the request in the first, the second request works fine. From the moment I execute ->get

requests for both clones, I get an error: I General error: 2031

clone

must create a deep copy of the original request, but something doesn't seem right.
Any ideas? Here is my request (it looks more complex than it is, and the request itself is fine):

    //Query dates 
    $query_onetime = clone $query; 
    $query_onetime = $query_onetime->join('events_dates', function($join) use ($input_date_start, $input_date_end){ 
                $join->on('events.id', '=', 'events_dates.event_id'); 
                    $join->where('events_dates.start_date', "<=", $input_date_end); 
                    $join->where('events_dates.end_date', '>=', $input_date_start); 
            });

            ->groupBy('events.id')
            ->get(); 

    if(isset($data["include_recurrent"]) && $data["include_recurrent"]){

                $temp_date_start = $input_date_start; 

                while(strtotime($temp_date_start) < strtotime($input_date_end)){ 
                    $temp_date_start = date('Y-m-d', strtotime($temp_date_start . " +1 day")); 
                    //Create a raw query string

                } 
                $join->whereRaw($query_string); 
            });

                ->get(); 

        $events = array_merge($events_onetime, $events_recurrent); 

      

        
        
        
      

    

EDIT: For information on request, here is the complete request.
I avoided this because it is quite long.
