Bruno Chareyre proposed the following answer:
Hi Reza,

You can find similar loops in many places, then you will see that they contain this kind of test:
if(!I->isReal()) continue;

and actually, it is the way to filter out interactions you are looking for, I think.
Your code segfaults because the dead interactions that stay there have no geometry and no physics (hence no normalForce either).

Bruno
