roofit 2.95 versus roofit 3.00

Dear root talkers,

*i did a minimum example of using roofit that works with roofit 2.95, but that crashes for roofit 3.00.

{ //works with roofit2.95, crash with roofit 3.00

   //example of program here :/afs/cern.ch/user/e/escalier/public/Minimum/    TFile f_test("mydata.root");
   TTree* mytree=(TTree *)f_test.Get("PAUReco");    RooRealVar ph_shwr_fracm("ph_shwr_fracm","ph_shwr_fracm",0.,1.,"GeV");    RooDataSet roodataset_test("roodataset_test","roodataset_test",mytree,ph_shwr_fracm);    cout << "entries=" << roodataset_test.numEntries() << endl; }

Would somebody know what is the problem ?

with 2.95, it works
(Unfortunately, the computer (not my computer) i wish to use has roofit 3.00 only installed)

with 3.00, it gives a crash :
CINT/ROOT C/C++ Interpreter version 5.17.00, Dec 21, 2008 Type ? for help. Commands must be C++ statements. Enclose multiple statements between { }.

The program is running. Quit anyway (and detach it)? (y or n) [answered Y; input not from terminal]

*In addition, would somebody has a example on how to create a RooDataSet from a given file with a given Tree inside. I see for example that the example in the roofit users manual 2.07-29, page 8, unbinned dataset, is wrong : ("x" must be after "tree", not the opposite).

==>if i do :
RooRealVar myobservable("myobservable","myobservable",0.,1.,"GeV"); RooArgSet list_of_observables(myobservable); RooDataSet roodataset_test("roodataset_test","MyFileThatContainsTheTree.root","NameOfTheTree",list_of_observables);

it doesn't work (whereas this kind of instruction was working 3 years ago...)
