Hi Simon,
the TROOT object has to live as long as the main() program (or at
least as long as the last ROOT object). In your case TROOT goes out of
scope at the end of the RootWriter::store_tracks() method while some other
ROOT objects still stay alive like bestand and Boom. Try putting
TROOT as first line in main(), or as global object just before main.
Does the problem persist in that case?
Cheers, Fons.
