我在读入ini文件的关键字列表时怎么提示出现抽象错误？这是怎么回事？

Question

INI文件做成下面形式应该好处理了吧[Main]
MainCount=2[Main1]
NumCount=3
Num1=
Num2=
Num3=[Main2]
NumCount=4
Num1=
Num2=
Num3=
Num4=

用TStringList:
var
  Hostini:Tinifile;
  HostName:TstringList;
  filename:string;
  i:integer;
begin
  filename:=extractfilepath(paramstr(0))+'Host.ini';
  hostini:=tinifile.Create(filename);
  hostname:=tstringlist.Create;
  hostname.Add('asdf');
  try
    hostini.ReadSection('HOST',hostname);//在这里出现抽象错误，不知为什么
    combobox2.Items.Clear;
    for i:=0 to hostname.Count-1 do
    begin
      combobox2.Items.Add(hostini.ReadString('HOST',hostname[i],'HPFS2'));
    end;{for}
   combobox2.ItemIndex:=0;
  finally
    hostini.Destroy;
    hostname.Destroy;
  end;
