You can try the CINT command .reset or gROOT->Reset() before executing
an unamed macro. This sometimes is not sufficient. It may happen that the crash
happen during a memory management operation from which it is difficult to
recover.

We have never organized public courses at CERN, but have given several courses
outside. FNAL have been more active and have organized many public courses.
These courses are very well organized (thanks Suzanne) and are also
available from the Web site at:
http://www-pat.fnal.gov/root/
Suzanne distributed a CDROM with the video of her courses at the ROOT workshop
at FNAL. May be she has still a few copies left.
But I encourage you to start from the page above. It is full of interesting
material, exercises, etc.
