RooArgSet::writeToStream Leaks Memory

Roofit and RooStats

Sorry I meant to post this under Stat and math tools, could a moderator move it for me?

Hello,

The code below will leak memory, but if I comment the line where writeToStream is called, there is no leak. Does anyone know of a solution to this?

Thanks,
Lenny

RooRealVar *signal = new RooRealVar("signal", "signal", -2, 20);

RooRealVar *mean = new RooRealVar("mean",
                       "mean",
                       0,20);

RooRealVar *sigma = new RooRealVar("sigma",
                        "sigma",
                        0,20);

stringstream var_cache;

for(Int_t l=0;l<100000000;l++){
    cout<<l<<endl;
    sigma.setVal(l/50);
    RooGaussian *test_fit_model = new RooGaussian("test_fit_model","test_fit_model",*signal,*mean,*sigma);
    test_fit_model->getVariables()->writeToStream(var_cache, kFALSE);
    delete test_fit_model;
    var_cache.str(string());
    var_cache.clear();
    }

Moved.
