It's not necessarily a matter of COE; e.g., perhaps most of the energy was quietly dissipated via neutrinos, following Robin's suggestion. But if there is a nuclear transformation from not-iron to iron, and neutrinos were not a big factor, then the physics is straightforward: E = mc^2 = [ (mass of not-iron) - (mass of excess iron) ] c^2 = [delta mass] c^2 If for some reason this situation does not hold, then it seems to me that the CoE discussion comes up again.
