Fixed. 
The problem was TChartSeries.Delete method was double-destroying a Marks.Positions and Marks.Items instance (XE4 and up only).

Correct code is:

....
      if FPositions.Count>ValueIndex then
      begin
        {$IFNDEF D18}
        FPositions[ValueIndex].Free;
        {$ENDIF}

        FPositions.Delete(ValueIndex);
      end;

      if FItems.Count>ValueIndex then
      begin
        {$IFNDEF D18}
        FItems[ValueIndex].Free;
        {$ENDIF}

        FItems.Delete(ValueIndex);
      end;
....
