[fpc-pascal] TR: Strange Behaviour of TBits

[Julien Devillers]

Hello

 

I found a strange behaviour of TBits. Example : 

 

procedure TForm1.Button1Click(Sender: TObject);

var

  x:TBits;

begin

  x:=TBits.Create();

  x[0] := true;

  showmessage(inttostr( x.size));

  x[1] := false;

  showmessage(inttostr( x.size));

  x[2] := false;

  showmessage(inttostr( x.size));

  x[3] := true;

  showmessage(inttostr( x.size));

  x[4] := true;

  showmessage(inttostr( x.size));

end;                  

 

The above code returns 1, 2, 3, 3, 4 while it should return 1, 2, 3, 4, 5.

I Built a TMyBits class using strictly the TBits.inc file from fpc and... the bug does

not appear... !

 

I'm using lazarus 0.9.28.2 beta and fpc 2.2.4 with linux 64.

 

Did I miss something ?

 

regards

Julien
