Problems with datasets in RooFit

Hi all,

I am using the last version of Root, and when I try run the standard RooFit script intro8 .cc
(http://roofit.sourceforge.net/docs/classref/examples/intro8.cc.html) I get series of very strange errors related to filling of the datasets defined in the script. The complete output is showed below, in the end of message. I got the same errors in my private script... Does someone have some idea about what is happening? Is RooFit compatible with Root v5.16.00?

P.S.: What does this error mean?

   Error in <TTree::Fill>: Failed filling branch:d.c_lbl, nbytes=-1     This error is symptomatic of a Tree created as a memory-resident Tree     Instead of doing: 

       TTree *T = new TTree(...)
       TFile *f = new TFile(...)
    you should do:
       TFile *f = new TFile(...)
       TTree *T = new TTree(...)

Regards,
A. Augusto

"O mais corrente neste mundo, nestes tempos em que às cegas vamos tropeçando, é esbarrarmos, ao virar a esquina mais próxima, com homens e mulheres na maturidade da existência e da prosperidade, que, tendo sido aos dezoito anos briosos revolucionários decididos a arrasar o sistema dos pais e pôr no seu lugar o paraíso, enfim, da fraternidade, se encontram agora, com firmeza pelo menos igual, repoltreados em convicções e práticas que, depois de haverem passado por qualquer das muitas versões do conservadorismo moderado, acabaram por desembocar no mais desbocado e reaccionário egoísmo. Em palavras não tão cerimoniosas, estes homens e estas mulheres, diante do espelho da sua vida, cospem todos os dias na cara do que foram o escarro do que são."
