This function is no good. If you carefully look at its logic and think about the way cyclus works, it becomes apparent that compositionIsTracked returns -1 every time. And indeed - I checked with callgrind, and it does return -1 every time. compositionIsTracked needs to be deleted. It is just a performance reducer.
