Hi

Working in Mac OS X, 10.7.0
gcc version 4.2.1
ROOT v5.30/00

How to reproduce: open up a ROOT file containing a TH1D histogram:

root [0]
Attaching file file.root as _file0...
root [1] for(int i =1; i<= pileup->GetNbinsX(); ++i) {

(using the up arrows to search for a previous command triggers the crash).

Stack trace:

• Break *** segmentation violation

There was a crash.
This is the entire stack trace of all threads:
