Accessing .root file

Hi there,

I have been using a script on Windows 7 to access a .root file that contains a collection of histograms, but ROOT crashed. That script runs perfectly fine on my friend’s Windows (I think it’s Windows 8 ). Then I tried to run that script on Ubuntu through VMWare and here’s the result. Do you have any idea what might happen? I’m not sure if it is because of my laptop or not…

[code]root [5] .x PRF.C

*** Break *** segmentation violation

There was a crash.

I’m afraid we need your PRF.C script and your .root file in order to reproduce your problem (i.e. a minimal running example).
