I studied Your code and found where problem is: DataDescription need 
initialize through variable. Working code (seems that TRGBA comes from 
GraphicEx.pas, but webpage with that source cose is timeouted so i use 
TRGBAQuad instead):

uses IntfGraphics, LclType, GraphType;

{ TForm1 }

procedure TForm1.Button1Click(Sender: TObject);
procedure DumpMem(Data: PCardinal; Size: Integer);
var
   i: Integer;
   Color: TRGBAQuad;
begin
   for i := 0 to Size - 1 do
   begin
     Color := TRGBAQuad(Data[i]);
     WriteLn('Red: ', Color.Red, ' Green: ', Color.Green,
       ' Blue: ',Color.Blue, ' Alpha: ', Color.Alpha);
   end;
end;

var
   ImgReader: TLazReaderBMP;
   IntfImg: TLazIntfImage;

   aprasas: TRawImageDescription;

begin
   ImgReader := TLazReaderBMP.Create;
   IntfImg := TLazIntfImage.Create(0,0);


   //IntfImg.DataDescription.Init_BPP32_B8G8R8A8_M1_BIO_TTB(0, 0);

   aprasas.Init_BPP32_B8G8R8A8_BIO_TTB(0, 0); // there is
   IntfImg.DataDescription:=aprasas;          // solution


   IntfImg.LoadFromFile('red.bmp', ImgReader);

   DumpMem(PCardinal(IntfImg.PixelData), IntfImg.DataDescription.Height 
* IntfImg.DataDescription.Width);

   ImgReader.Destroy;
   IntfImg.Destroy;
end;
