Fitting of functions, folding of histos

Dear Rooters,
I've got a histo (hin) with small statistics. Before
fitting my own function (func) I'd like to smooth the
histo using pol9. So in fact I want to fit pol9 by
my own function.
What is the right way to do it?
I tried for example:
TF1 *hpol=new TF1("hpol","pol9(0)",0,m_max,npar);
hin->Fit("hpol","be");
TF1 *fpol=gROOT->GetFunction("hpol");
fpol->Fit("func","be");
TF1 *fun=gROOT->GetFunction("func");
but I received
Function:hpol cannot be compiled
*** Break *** segmentation violation
Next question - Is the folding of histos implemented in ROOT?
Best wishes,
Tadeusz
