--- Comment #3 from H.J. Lu <hjl.tools at gmail dot com> ---
s-os_lib.adb has

   function Write
     (FD : File_Descriptor;
      A  : System.Address;
      N  : Integer) return Integer
   is   
   begin
      return
        Integer (System.CRTL.write
                   (System.CRTL.int (FD),
                    System.CRTL.chars (A), 
                    System.CRTL.size_t (N)));
   end Write;

It is compiled into

jmp    write

'A' should be a pointer, not integer.
