Steps To Reproduceload game,
end turn
crashes during ai turn
Additional Information
Not sure about fuzzyHelper::
extern boost::thread_specific_ptr<CCallback> cb;
(could not find where cb variable would be written)

however at some point this variable is accessed instead of the one provided as argument (from AINodeStorage)
not sure sure if diff below is acceptable but somehow it solves the core for me (removed AIUtility::compareDanger since not used along the way)
