[ROOT] Seg fault

Dear Root
   I used TTree.MakeClass (what a nice tool !) to create a Loop on one of my TTrees.
 It works well on the root file that contained the original TTree.  I then chain together
 23 files with the same TTree in them.  I do newclass t(uDst) and it runs
 the whole dataset fine but after I am done with the session and type .q it seg. faults. 
 root does not seg fault when I do only the original file.  I am running on RedHat Linux
 I'll attach the chain macro, Chad.C
  My session is 
  *        W E L C O M E  to  R O O T       *
  *                                         *
  *   Version   3.10/01    8 October 2003   *
.x Chad.C
 .L newclass.C
 newclass t(uDst)
 t.Loop()

Here is the gdb  - 
root.exe [21] .q

Program received signal SIGSEGV, Segmentation fault.
