te pluginy podaja rozmiary w heksie co jest nieczytelne,
mi sjest potrzebny rozmiar kodu w kodzie w moich wlasnych produkcjach ot tak dla ciekawosci (mozna dostrzec ciekawe rzeczy np rozmiar .bss u mnie w niektorych libkach jest czasem zasakujaco duzy, a tak z glowy nie pamietalem ze az tyle tego alokuje)

machnalem jakiegos tam drafta testowego
