TNtuple doesn't fill after upgrading from ROOT version v5.22 to ROOT version v5.24

Hi,

  I upgraded to ROOT v5.24 today and ran into some problems with the TNtuple Class. The problem is that my TNtuple does not seem to get filled when using v5.24. If I am using v5.22 the Ntuple gets filled. Below is the simple code I am using, compiled with both libraries. The program's output is given too. For comparison I also fill a Tree, the filling of the Tree seems to happen without problem.

This is the relevant piece of my code::

       cout<<  "Reading file :: "<<  filename<<endl;
       datafile = new TFile(outfile,"RECREATE");
       datantuple = new TNtuple("datantuple",filebase,"a1");
       dattree = new TTree("dattree",filebase);
       dattree->Branch("a1",&a1);
       nlines=0;
        in.open(filename);
         while (1) {
           in>>  a1 ;
           if (!in.good()) break;
             datantuple->Fill(a1);
             dattree->Fill();
             nlines++;
           }
        printf(" found %d points\n",nlines);
        cout<<  dattree->GetEntries()<<  " Tree entries"<<endl;
        cout<<  datantuple->GetEntries()<<  " Ntuple entries"<<endl;

I compile it using:

   g++ -Wall -W -g -DDEBUG -fPIC -Wall -W -g -DDEBUG -fPIC -pthread
-m64 -I/home/products/root/root_v5.24.00/include -O3
-L/home/products/root/root_v5.24.00/lib -lCore -lCint -lRIO -lNet -lHist
-lGraf -lGraf3d -lGpad -lTree -lRint -lPostscript -lMatrix -lPhysics
-lMathCore -lThread -lGui -pthread -lm -ldl -rdynamic readdata_deb.C -o
readdata_deb

The output then gives:

   ./readdata_deb -f ./testt.txt
  Reading file :: ./testt.txt
  found 1000 points
1000 Tree entries
0 Ntuple entries

--> The Ntuple is empty !

If I compile it using the v5.22 libs::

   g++ -Wall -W -g -DDEBUG -fPIC -Wall -W -g -DDEBUG -fPIC -pthread
-m64 -I/home/products/ROOT/new/include/root -O3
-L/home/products/ROOT/new/lib/root -lCore -lCint -lRIO -lNet -lHist
-lGraf -lGraf3d -lGpad -lTree -lRint -lPostscript -lMatrix -lPhysics
-lMathCore -lThread -lGui -pthread -lm -ldl -rdynamic readdata_deb.C -o
readdata_deb

The output now is:
Reading file :: ./testt.txt
  found 1000 points
1000 Tree entries
1000 Ntuple entries

--> The Ntuple has 1000 entries

Could somebody explain what is going on ?

  Thanks a lot for your time,
