Hello Rooters, I got some troubles by trying to change the Event class (in the ROOT test/ dir.). I just added a member to the class Track : TMatrixD fCovariance; so that the Track constructor is now : Track::Track(Float_t random) : TObject() , fCovariance(5,5) Since creating a TMatrixD allocates memory, I need to change the Event Clear() method by replacing the line : fTracks->Clear("C); by : fTracks->Delete() ; otherwise I get a memory leak. I then compile and run the exe Event : ./Event 1000 1 1 1 to create a Event.root file. everything works fine until here. If then I re-run the exe : ./Event 1000 1 1 0 just to read the Event.root file or if I execute I get a huge memory leak. By checking the file MainEvent.cxx, I see that in the reading mode (read ==1), there's no call to the Event Clear() method , is this correct ?? I thought not and added this call, thinking it would reduce the memory leak, but on the contrary it's even worse (the effect is the same using the macro eventa.cxx which does the same stuff). Could so tell me where I did something wrong ? thanks, seb. I put a tar.gz file to reproduce the pb under : /afs/in2p3.fr/home/g/greder/public/Event_pb.tar.gz I'm running under RH 7.2, gcc 2.96, ROOT version 3.03.09 (I'm checking if I get the same pb with 3.05.05)
