[ROOT] Core dump using Root 4.00-08 in TTree:SetName()

Hi,

first here is my exact configuration:
 - OS: Red Hat Enterprise Linux WS release 3 (Taroon Update 2)
 - ROOT: Intel x86 Linux for Redhat RHEL 3 (SLC3) and gcc 3.2.3,
   version 4.00/08
   (ftp://root.cern.ch/root/root_v4.00.08.Linux.RH7.3-slc3.gcc3.2.3.tar.gz)
 - gcc: gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-34)

and I have the following small program:

#setName.C
#include "TTree.h"

int main() {
  TTree *tree1 = new TTree();
  tree1->SetName("tree1");
  TTree *tree2 = tree1->CloneTree(0);
  tree2->SetName("tree2");
}

I compile it with
      gcc -ggdb `root-config --cflags --libs` setName.C
and run a.out. I get the following seg fault:

 *** Break *** segmentation violation
 Generating stack trace...
 0xb6405768 in __libc_start_main + 0xf8 from /lib/tls/libc.so.6
 0x08048fad in dl_iterate_phdr + 0x31 from a.out

Using gdb gives:

[Thread debugging using libthread_db enabled]
[New Thread -1240223072 (LWP 26487)]

Program received signal SIGSEGV,
Segmentation fault. [Switching to Thread -1240223072 (LWP 26487)]
0x080490fe in main () at setName.C:8
8      tree2->SetName("tree2");
(gdb)


Somehow SetName() of the cloned tree produces the seg fault. Any
advice/workaround for that?

Thanks a lot,
Frank
