[ROOT] problem with recursive filling of histograms

Hello rooters!
I'm trying to fill histograms named "si" (where i is an integer) with 
the following piece of code but I get this message:

"Warning in <TH1::GetBinContent>: this method must be overridden!"(times 
the number of histograms)


"Warning in <TH1::GetBinContent>: this method must be overridden!" 
(times the number of histograms)

  and it seems to enter an endless loop since it shows regularly the 
warning message (even after a ctrl C).Moreover the histogram seems not 
to be filled.


here is the piece of code:
{
float xbins[21];
float xint=(50.-.1)/20.;

h1= (char *) calloc(10,sizeof(char));
h2= (char *) calloc(10,sizeof(char));

for(int ij=0;ij<21;ij++){
   xbins[ij]=.1*pow((50./.1),(float)ij / 20.);
}
for(int i=1;i<7;i++){
   int id1=i;
   sprintf(h1,"s%d",id1);
   TH1::TH1(h1,h1,20,xbins);
}

   for(int i=1;i<7;i++){
     int id1=i;
     sprintf(h2,"s%d",id1);
     TH1 *h3=(TH1*)gROOT->FindObject(h2);
     h3->Fill(xbins[i]);
   }


}
