[ROOT] Problems with array->Delete()

Dear rooters,

I am running into the following problem. I have an TObjArray (of
TLorentzVectors) which I initialise in the Begin method:

    m_Hadrons_Lab = new TObjArray;

in ProcessCut I delete, for safety

    m_Hadrons_Lab->Delete();

and fill

      for( ... some loop ... )
      {
	  m_Hadrons_Lab->Add(new
             TLorentzVector(p1,p2,p3,p4);
      }

I perform further operations on this array in processFill and ProcessCut
(looping, printing etc.), ut nothing serious.

In Terminate, I finally delete:

  m_Hadrons_Lab->Delete();
  delete m_Hadrons_Lab;

Since some time I get a seg fault in the Begin method where I try to do
the ->Delete() ... Studying the array directly before the Delete() command
shows that it is 'healthy' and contains the elements given to it in the
previous ProcesFill call ...

Can anybody tell me what is going on here ?

Cheers, and thanks,

Thomas
