Subject: Problem writing histograms in Maker


Hi,

I have a few histograms defined in my Maker.  I want to write them out, so
I use:

Int_t StDaveMaker::Finish() {
  TFile* out = new TFile("dave.root","RECREATE","Dedx Histograms");
  out->cd();
  m_dedx_vs_rigidity->Write();
  out->Close();
  return kStOK;
}

where m_dedx_vs_rigidity is a pointer to a TH2F.

For some reason, when I run this ROOT aborts.  Does anyone know what might
be going on?

Thanks,

dave
