[ROOT] Trasfert of file RH72/ROOTv3.05.04 -> RH73/ROOT v3.05.04

Dear developers,

I have produced a ROOT TTree/TFolder structure saved on a TFile with ROOT 
v3.05.04 under linux RedHat 7.2 with gcc 296. This file is well treated 
afterwards under other machine running the same RedHat version and ROOT 
version.

But, transfering the File under LXPLUS running RH73 and compiling my 
application with
/afs/cern.ch/sw/packages/ROOT/v3.05.04/rh73_gcc296

I get a Abort that valgrind diagnostic is

==6757== Jump to the invalid address stated on the next line
==6757==    at 0x0: ???
==6757==    by 0x41C5E512: __dynamic_cast_2 (in 
/usr/lib/libstdc++-3-libc6.2-2-2.10.0.so)
==6757==    by 0x40799928: RTSCINHit::LocalParticle(void) 
(../OpRData/RTSCINHit.cpp:30)
==6757==    by 0x402CEBBE: Tree2Tree::create(RTSCINHit *) 
(../OpIO/Tree2Tree.cpp

The statement pointed is

RParticle* RTSCINHit::LocalParticle() {
  return dynamic_cast<RParticle*>(fLocalParticle.GetObject());
}

That is to say the TObejct* stored as a TRef is not recognized anymore. Do 
you have a comment on the trasfert of file created and than treated under 
two different of machine systems ?
