hi tony,

as far as I can see there are a few issues with your code:

- you should not use setsubset with collections of elements that you created -> this will result in corrupt LCIO files
(l.278)

- a memory leak in ee_Durham_Jet_Finder_Exclusive (l. 158):

you create a new particle on the heap every time you combine two particles but in the end you only add n jet particles to the collection
-> you need to delete the intermediate ReconstrucetParticles (possibly in CombineParticles)

- the follwoing will result in an undefined pointer in the LCIO file (if the vector is empty the first element is undefined):

   if(p1_particles.size()==0)
    {
      jet->addParticle( p1_particles[0] );
    }

hope this helps to find your problem.

Cheers, Frank.
