Key to Flags:
  W (write), A (alloc), X (execute), M (merge), S (strings)
  I (info), L (link order), G (group), x (unknown)
  O (extra OS processing required) o (OS specific), p (processor specific)

I check binary by binutils objcopy and elfcopy. 

15, 16, 23 section missing swap copy by elfcopy.

Thanks
