Hello,
I have been using 4.02/0 for several months now and have just started testing my code w/ 4.04/02 (win32gdk) I build my application that uses root w/ MSVC++.net 2003 and I built the root libraries from sources with the same compiler.
My application reads root files created with root version <=4.02/0 - these files contain a TTree. The application creates 2 memory resident TTrees: one is a sampled version of the original, the other is a friend. Before I switched to 4.04/02, I had no error messages, after switching to 4.04/02, I get a bunch (tiny fraction of Fill calls give them but I do get them for both the sampled tree and the friend tree) Here’s how the sampled TTree is created (the unsampled TTree is m_ntRawFull):
m_ntRawFull->SetBranchStatus("*",1);
m_ntRawSampled = m_ntRawFull->CloneTree(0);
m_ntRawSampled->SetName("ntf");Here’s how the friend tree is created:
m_ntCorr = new TTree("ntCorr",m_pchTitle);
m_ntCorr->Branch("tofc",&m_Tofc,"tofc/F");
m_ntCorr->Branch("mass",&m_Mass,"mass/F");
m_ntCorr->Branch("cut",&m_Cut,"cut/S");
m_ntCorr->Branch("tofb",&m_Tofb,"tofb/F");
m_ntCorr->SetBranchStatus("*",1);
m_ntRawSampled->AddFriend(m_ntCorr);and here’s the Filling loop:
for(int i=0;i<m_ntRawFull->GetEntries();i+=skip)
{
m_ntRawFull->GetEntry(i);
.
. calculate stuff for friend tree...
.
.
m_ntRawSampled->Fill();
m_ntCorr->Fill();
}
And here is a sampling of the errors I get:

Any help would be greatly appreciated…
