[ROOT] TF1 problems

Hi,

I have a piece of compiled code in which I fit a parabola to a histogram.
This fit is done once for every pseudoexperiment and everything works
fine. However, once my compiled code has finished if I try to fit a
histogram from the ROOT prompt I get a segmentation violation. This only
happens when I run my code for more than one pseudoexperiment.

Here it is the code:

TH1F *h1 = new TH1F("h1", "Likelihood", 1900, 120.0, 230.0);

for (int j = 0; j < pseudo; j++)
{
  ...

  TF1 *parabola = new TF1("parabola", "pol2", low_limit, high_limit);
  h1->Fit("parabola", "Q0R");

  ...

  delete parabola;
}

Thank you for your help.

Carlos
