[Brahms-dev-l] Issue with Histogram flag

Brahms,
 
CAN ANYONE HELP ME???


  I do not understand a bug that I have in my code.  It has to do with the BrModule fHistOn flag that one should be able to set using either 
BrModule::SetHistOn() or BrModule::SetHistOff().
 

  Here is my issue.  I define a flow module

BrFlowModule *flsi3mod = new BrFlowModule("flow3","flsi*_3");  flsi3mod->SetHistOff(); 
flsi3mod->SetTreeOn(kTRUE);
appModule->AddModule(flsi3mod);

In BrFlowModule::DefineHistograms(), I have

  if (HistOn()) {
    hVtx = new TH1F("hVtx","Vertex location",500,-100,100);
...
}


Then in BrFlowModule::Event(BrEventNode* inNode, BrEventNode* outNode)
there is
  if (HistOn()) {
    cout<<"Histogramming is ON!!!"<<endl;
    hVtx->Fill(fVertex);
 }


When I run the code, I get the message 
Histogramming is ON!!! 
and a segmentation violation.

I know how to fix the problem, but I am more or less looking for anyone who has seen this same problem and what they did to fix it.  


Erik
