After switching to version 4.01/02 I have encountered now a more severe
problem: at run time my code causes a bad crash.
I'm trying to fill an ntuple with TVectors:
TVector *ch;
TVector *hit;
ntpT->Branch("hit","TVector",&hit,32000,0);
ntpT->Branch("ch", "TVector",&ch ,32000,0);
This code did ran just fine with Version 3.05/07.
Do I need to use a different syntax?
Thanks again for your help.
