TTree::Branch segmentation violation if splitlevel = 0

[Wile E. Coyote]

Why?

Code: Select all

{
  TVector3 Pos(1, 2, 3);
  TFile *f = TFile::Open("test.root", "recreate");
  TTree *t = new TTree("tree", "tree with vector");
  t->Branch("Pos", &Pos, 32000, 0); // segmentation violation if splitlevel = 0
  t->Fill();
  t->Write();
  delete f;
}

Hi,

This particular combination was broken (i.e. can not use TVector3 with split level 0). This is corrected in the v5.34 patch branch (5.34/06 and up) and in the trunk.

Thanks for reporting this issue.
Philippe.
