multiple plots with multiple stat boxes in one canvas

Hi all!

   I'm using ROOT 5.18 on my laptop.
I'd like to create multiple plots with multiple stat boxes in one canvas and found http://home.fnal.gov/~asmoron/roottips.html#stat_box

   But actually it works just if I give commands from command line. By using a routine, it does not work even if I try to modify just the text color of one stat box... The input file is really simple, since it is just a trial.

#include <cstdlib>
#include <cstdio>
#include <iostream>
#include <fstream>
#include <string>
#include <vector>
#include <sstream>
#include <cmath>
#include "TColor.h"
#include "TStyle.h"
#include <TFile.h>
#include <TCanvas.h>
#include <TH2F.h>
#include <TSystem.h>
#include <TPave.h>
#include <TPaveStats.h>

using namespace std;

void trial() {

     TFile *f_s=new TFile("file1.root","read");
     TH1D*h_s=(TH1D*)f_s->Get("proj");
     h_s->Draw();

      TPaveStats *p =
(TPaveStats*)h_s->GetListOfFunctions()->FindObject("stats");
      p->SetColor(2);
      p->Draw();
      f_s->Close();

}

By activating the gdb debugging, I obtain the following error message. Program received signal SIGSEGV, Segmentation fault. 0x00007ffff32454cd in trial () at

(gdb) info locals
f_s = 0x964c50
h_s = 0xb6f070

Could anyone help me, please?

Thank you,
