ifstream.close problem

Im trying to do this in dev c++

Im basically open a large list which contains filenames to parse
and store the results.

Now what im trying to do here is to open an close a file in order to be able to "parse" a number of files (which are saved in a list)

Code:

---


 ifstream l_file("list.txt"); //text containing list of files.
  ifstream a_file; //the file to be parsed
  ofstream b_file("final.txt"); //file which will be filled with the result

  while (!l_file.eof()) //open the file list
  {
  l_file>>fname; //send the file to the filename
  a_file.open(fname); //open the text containing emails
  cout<<"filename:"<<fname<<":"<<a_file.is_open()<<endl;
  while (!a_file.eof())
  {
        a_file>>str;
        if (parseline(str)!='\0')
        {
            cout<<"linea:"<<str<<endl;
            cout<<"lineap :"<<parseline(str)<<endl;
            b_file<<parseline(str)<<endl;      //save the parsed data
        }
  }

  a_file.close();
  a_file.clear();
  }
  l_file.close ();
  b_file.close ();

getch();
return 0;
}

It looks like it should work right? well when I try to open the a_file for a second time, the program crashes. thats why I added a_file.clear but it doesnt work. is there a way to use an ifstream with 2 diferent files without crashing? how do you actually close a filestream?

p.s.
oh yeah, the list contains the same file like this

example.txt
example.txt

so is not a file missing problem.

Read that, and come back.

Sorry first time here, I used the code tag now . :D

Now what can I do to close the ifstream?
