Hello.
I parse a big data files and i catch a memory leak after TFLRE.Free() like this:

At Eureka mem leak log it's see like this:

I inspect, what count of execution of this block

is more, than count of execution of this block:

and i change free memory block to this code:

 for State in AllStates do begin
  if not Assigned(State) then
    Continue;
  SetLength(State^.SubMatches,0);
   Finalize(State^);
  FreeMem(State);
 end;
 FreeStates:=nil;

Memory leak is gone out. Does it's right decision?
Sorry for my bad English, it's not my native language.
