ROOT crashes when writing a large TVectorF object

Hi,

ROOT 4.04/02 crashes when writing a large TVectorF object (for instance 512*512*1273) to a TFile.

The Write function works OK for small TVectorF objects (up to 176470011 elements):

$ cat t1.C

void t1()
{
  TFile f("t1.root", "recreate");
  TVectorF vec(176470011);
  vec.Write("vec");
  f.Close();
}

$ root

root [0] .x t1.C // Works OK
root [1]

But it crashes for larger TVectorF objects:

$ cat t2.C

void t2()
{
  TFile f("t2.root", "recreate");
  TVectorF vec(176470012);
  vec.Write("vec");
  f.Close();
}

root [0] .x t2.C // Crashes
$

ROOT is terminated and no error message is printed out. Similar behavior was observed with root-4.03.04 but the maximum TVectorF size was different.

Tested on: SUSE Linux 9.1, x86, 2GiB RAM, ROOT 4.04/02 was compiled with GCC 3.3.3.
