There appears to be a bug in the streamer of TObjArray in root 3. The
following code works in root 2.25 but crashes in root 3.
{
// make object array: 10 entries, index 5 to 15
TObjArray* oa = new TObjArray(10,5);
for (Int_t i=0; i<10; i++) {
TObject* o = new TObject();
oa->Add(o);
}
// write to file and crash
TFile f("test.root","recreate");
f.cd();
oa->Write("array",TObject::kSingleKey);
f.Close();
}
Changing the line in TObjArray::Streamer (root3) from
nobjects = GetLast()+1;
back to what it was in root2.25
nobjects = GetSize();
Should fix the problem.
Was there a reason for this change?
