Problem with compiled program in Root V4.00/08 which works fine in ROOT V3.10/02

I prepared a demo for my students sometime back with Root V3.10/02 and the demo seems to be working fine, until I migrate the exact same program and compile it on Root V4.00/08. It compiles and links without a problem.

I have attached the tarred zipped folder that contains the demo. The folder contains
a README file for instructions on compiling/linking the programs in the folder.
Can anyone please reproduce the problem on their machine and let me know if you have an explanation? Thank you for the help in advance
