Hello!

When I try to replace a pattern by an empty string, I get an access violation (FPC 2.6.4, Windows).

program testreplace;

uses
  Classes, SysUtils, FLRE, FLREUnicode;

begin
  with TFLRE.Create('\d', []) do
  begin
    MaximalDFAStates := 65536;
    WriteLn(Replace('a1b', '-'));
    WriteLn(Replace('a1b', '')); // Access violation
    Free;
  end;
end.

Best regards.

Roland
