[ROOT] Problems with ROOT v3.04.01 ?

Hello everybody,
 I have tried the new release of ROOT. I am facing some problems I did not
have on version 3.03.09.

 1.When compiling a routine or a class using TVector3, I obtain the
   following warning:

cxx: Info: /cern/root/include/TMatrix.h, line 343: function
          "AreCompatible(const TMatrix &, const TMatrix &)" redeclared
          "inline" after being called
inline Bool_t AreCompatible(const TMatrix &im1, const TMatrix &im2)
--------------^

 2. When I use a TTreeViewer tu analyse the data in a TTree using a class,
the behaviour of the TTree is somewhat erratic: ROOT stops with a
segmentation fault a random times.
 
 3. when plotting bidimensional histograms, the "ZCOL" option generates
floating point exceptions each time the TPad is updated (after a zoom on
one axis or after defining a Graphical Cut). 

 4. when I use a TSelector (here Exo1) to analyse a TTree (generated with
former versions of ROOT, 3.03.09 or 3.02.07), I obtain the following 
warning: 

cxx: Warning: /data2/cussol/Jour5/./uaaCHdKIP.cxx, line 61: statement
either is
          unreachable or causes unreachable code
      Assert(sizeof(::Exo1) == sizeof(ROOT::Shadow::Exo1));
------^

The TTree I use and the Classes Fragment (not forget to load the
libPhysics.so library) and Event are present in the tarball at the
following URL: 

	http://caeinfo.in2p3.fr/root/Formation/Jour5.tar.gz


 I am the only one to face these problems/features? Could it be due to the
system I use (TRUE64 on a Dec/Compaq)? 

 I run root v3.04.01 compiled with cxx on a DEC/COMPAQ alpha under TRUE64.

 Thank you for your help.
