Hi Rooters I am working with ROOT -Version 3.10. and I am trying to obtain some fit-results (the values 'vlow' and 'vhigh'). Thetefore I am using the method TVirtualFitter::GetParameter(Int_t ipar, char* name, Double_t& value, Double_t& verr, Double_t& vlow, Double_t& vhigh) My program: // creating histogram TH1F* h1=new TH1F("h1","histo from a gaussian",100,-3,3); h1->FillRandom("gaus",10000); // fitting TF1* f1=new TF1("func1","gaus",0,10); h1->Fit("func1"); char* dummy; Double_t v1=0; Double_t v2=0; Double_t v3=0; Double_t v4=0; // getting current fitter TVirtualFitter* hFitter = TVirtualFitter::GetFitter(); // *** segmentation fault here *** hFitter->GetParameter(1, dummy, v1, v2, v3, v4); Why do I have a segmentation fault when trying to obtain the fit-results?
