Simba or PS or My Scripting problem

Been messing with plugins for Simba and noticed Simba Errors when you free a TStringList

or there is a problem with this function =0

function OS: string;
var 
  AProcess: TProcess;
  AStringList: TStringList;
  I: integer;
begin
  AProcess := TProcess.Create(nil);
  AProcess.CommandLine := 'uname -a';
  AProcess.Options := AProcess.Options + [poWaitOnExit, poUsePipes];
  AProcess.Execute;
  AStringList := TStringList.Create;
  AStringList.LoadFromStream(AProcess.Output);
  AProcess.Free;
  Result := '';
  for I := 0 to AStringList.Count - 1 do
    Result := Result + AStringList.Strings[I];
  AStringList.Free; // <- Error Here
end;

Try


function OS: string;
var
  AProcess: TProcess;
  AStringList: TStringList;
  I: integer;
begin
  AProcess := TProcess.Create(nil);
  AProcess.CommandLine := 'uname -a';
  AProcess.Options := AProcess.Options + [poWaitOnExit, poUsePipes];
  AProcess.Execute;
  AStringList := TStringList.Create;
  AStringList.LoadFromStream(AProcess.Output);
  Result := '';
  for I := 0 to AStringList.Count - 1 do
    Result := Result + AStringList.Strings[I];
  AStringList.Free; // <- Error Here
  AProcess.Free;
end;

Mabye, ill look into cross compiling and make a windows one and test in wine.

Whats a command to bring up the version of windows?

Extreamly weird lazarus will cross compile me simba.exe but trying to natively compile it i get

../../Units/PascalScript/uPSI_Dialogs.pas(30,4) Fatal: Can't find unit Windows used by uPSI_Dialogs
