Hi Rooters, These are two oddities (bugs?) in the code (ROOT 2.24/05): 1) for SetBranchStatus: When the status of a branch (A) in a TClonesArray is altered the corresponding LeafCount() is activated independently of what we are doing to the branch (A). IMHO this LeafCount() branch should only be activated when (A) is being activated but not when it (A) is being deactivated. Otherwise one has to write some weird code in order to deactivate all branches in a TClonesArray, which is needed under certain circumstances. (namely, trying to read a Tree with not all the classes in the Tree's TClonesArrays being added to the dictionary) Or am I missing something? (P.S: Maybe it is not obvious but with "activate" I mean setting status to 1 and deactivate means setting status to 0) 2) for TChain::LoadTree When a entry is asked which is not available in all the trees of the chain (i.e. entryNumber > chain.GetEntries() ). The LoadTree() function deletes the currently file opened and returns an error code. That's perfect, but when deleting the file the "fFile" pointer is not set to 0, therefore in the destructor of the class if (fFile) delete fFile; calls the TFile destructor a second time delivering a SEGV Best Regards, Manuel --------------- Manuel Sanchez Garcia (manuel@fpddux.usc.es) Univ.
