DemoGoogleMaps raise an Exception during TGPolygon.Destroy

[GoogleCodeExporter]

Hello!

1. Start DemoGoogleMaps.exe
2. Press second Polygon button
3. Close application

Exception class EInvalidPointer with message 'Invalid pointer operation'. 

TfrmMain.btnTestPolyGon2Click has code:

      PolyLine.AddPoint(Location);
      Marker := TGMarker.Create(
                  Location,
                  GoogleMaps1,
                  'This is point '+IntToStr(I),
                  'http:...'
                );

Location is destroyed in TGMarker.Destroy
and then in TGPolygon.Destroy.
