   # Proposed changes
   
   Issue Number: close #xxx
   
   ## Problem summary
   
   The mem tracker using mem hook statistics cannot guarantee the accuracy, 
because the memory transfer between function cannot be enumerated.
   
   This is often misleading in real production environments, so these 
inaccurate mem trackers are only printed when `memory_debug=true`.
