Hi,
The ROOT is 3.02/07 on a RH6.2 with egcs-1.1.2.

root [0] TFile *f = new TFile("Vacuum.250.15.root") // file with NS TNtuple
root [1] NS->Print()
******************************************************************************
*Tree    :NS        : NS                                                     *
*Entries : 13171875 : Total =       739067272 bytes  File  Size =  227480705 *
