In http://husio.homelinux.com/blog/post/gdb-przyklad-uzycia/ we have:
(gdb) p printf("\"%s\"\n",
gtk_combo_box_get_active_text(app_conf->input_device))
I call: p OB.GETN and I see: "Cannot take address of method GETN"
My code is
Code: [Select] TMyClass=class
  private
    n: integer;
  protected
    function GetN: integer;
  public
    pubVar: integer;
    property PropN: Integer read GetN;
  end; 
function TMyClass.GetN: integer;
begin
  result:=n;
  inc(n);
end;

var
  ob: TMyClass;
  n: integer;
begin
  ob:=TMyClass.Create;
  n:=ob.PropN;
  n:=ob.PropN;
  ob.Free;
end.

(gdb) disassemble shows me:
p TMYCLASS__GETN - shows function address
p TMYCLASS__GETN(OB) - call ob.GetN
I think better name for TMYCLASS__GETN should be TMYCLASS$GETN because
_ is legal ident char

See if this works better if you give

set language pascal

first.
