I cannot use my ROOT-based analysis on my laptop due to a buffer overflow in rootcint (see below). However, it works in other environments (SLC5 64 bit and Debian 64 bit).
You could try rootcint -f VBFStudyDict.cxx -c VBFStudyGUI.h VBFStudy.h NTupleChain.h EventCutset.h Plotset.h Utilities.h LinkDefFile.h You could also try to use the tool named ‘valgrind’ to pin-point the location of the error.
one of your class names is too long, probably because of a template with plenty of default parameters. You can track down which one it is by only passing one header after another. You can then send us output.txt from g++ -E HeaderThatCausesIt.h -I$ROOTSYS/include > output.txt so we can figure out which type is causing it.

unfortunately it looks like my guess where wrong
Try again with-I$ROOTSYS/lib/root/cint/include -I$ROOTSYS/lib/root/cint/lib -I$ROOTSYS/lib/root/cint/stl

(I am not yet managing to reproduce the error … i.e. the dictionary is created just fine from me ). So can you try:valgrind rootcint -f VBFStudyDict.cxx -c VBFStudyGUI.h VBFStudy.h NTupleChain.h EventCutset.h Plotset.h Utilities.h LinkDefFile.h
Well, it also works okay for me on an SLC5 system. But life would be easier if it also worked on my laptop. Please find below the valgrind output.
valgrind rootcint -f VBFStudyDict.cxx -c VBFStudyGUI.h VBFStudy.h NTupleChain.h EventCutset.h Plotset.h Utilities.h LinkDefFile.h

The problem is most likely the triple!!! nested map:map<unsigned int,map<string,map<unsigned int,short> > *>When CINT explicits the 3rd and 4th argument of the maps, the total size name is more than 512 characters!
To solve the problem you need to #define G__LONGBUF
in G__ci.h (and recompile root).
