I think your seeing branches that occur in inlined functions. Try using printf(...) instead of cout<< along with moving functionABC to an out of line function (asumming -O0) and I think the results will make more sense. And for the last 3, I think it is due to the virtual destructors, perhaps a resudual of potential multiple inheritance?
