Internal compiler error

[mikes@nilenet.com]

g++ -v reveals version: 2.95.2

I have a pIII 500 with redhat linux, all the latest updates from
updates.redhat.com as of Jan24.

I compiled like this: $  g++ 13-7.cpp -o 13-7

  AND GOT THIS:

mylist.h: In method `void
List<Pair<int,basic_string<char,string_char_traits<char>,__default_alloc_template<true,0>
> > >::print_all() const':
13-7.cpp:50:   instantiated from
`Set<int,basic_string<char,string_char_traits<char>,__default_alloc_template<true,0>
> >::print()'
13-7.cpp:66:   instantiated from here
mylist.h:49: Internal compiler error.

It isn't more than 150 lines so I pasted it below, two files 13-7.cpp
and mylist.h
my main problem was struct Pair, I was trying to overload operator
<<() to work properly.
Please send me feedback on how to get operator<< to work for struct
Pair.

here is 13-7.cpp:
//----------------------------------------------------
#include <iostream>
#include <string>
#include "mylist.h"
using namespace std;

template<class key,class value> struct Pair;
template<class key,class value> class Set;

template<class key,class value>
struct Pair
{
  key k;
  value v;
  template<class key2,class value2> friend ostream& operator<< (ostream&
ls, const Pair<key2,value2>& rs);
//    {
//      ls << rs.k << '\t' << rs.v;
//      return ls;
//    }
};

template<class key,class value>class Set
{
public:
  void add(const key& new_key, const value& new_value);
  void print();
private:
  List<Pair<key,value> > _set;
};


template<class key,class value>
template<class key2,class value2>
ostream& operator<<(ostream& ls, const Pair<key2,value2>& rs)
{
  ls << rs.k << '\t' << rs.v;
  return ls;
}

template<class key,class value> void Set<key,value>::add(const key&
new_key, const value& new_value)
{
  Pair<key,value> temp;
  temp.k = new_key;
  temp.v = new_value;
  _set.add(temp);
}


template<class key,class value> void Set<key,value>::print()
{
  _set.print_all();
}

int main()
{
  Set<int,string> test;
  int tempi = 0;
  string temps;
  for(int a = 0; a < 10; a++)
    {
      cout << "Enter an integer: ";
      cin >> tempi;
      cout << "Enter a string: ";
      cin >> temps;
      test.add(tempi,temps);
    }
  test.print();
}
//^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AND HERE IS mylist.h:
//-------------------------------------------------
#ifndef MYLIST_H
#define MYLIST_H

#include <iostream>
using namespace std;

template<class T> class List
{
  struct Link
  {
    Link(const T& init_val);
    Link* next;
    Link* prev;
    T data;
  };
  Link* first;
  Link* last;
public:
  List();
  ~List();
  void add(const T& new_data);
  void print_all() const;
};

template<class T>List<T>::Link::Link(const T&
init_val):data(init_val),next(0),prev(0){}

template<class T> List<T>::List()
{
  first = 0;
  last = 0;
}

template<class T> void List<T>::add(const T& new_data)
{
  Link* new_link = new Link(new_data);
  if(!last)
    last = new_link;
  else
    first->prev = new_link;
  new_link->next = first;
  first = new_link;
}

template<class T>void List<T>::print_all() const
{
  Link* temp = first;
  while(temp)
    {
      cout << temp->data << endl;
      temp = temp->next;
    }
}

template<class T>List<T>::~List()
{
  Link* temp = first;
  while(temp)
    {
      Link* temp2 = temp;
      temp = temp->next;
      delete temp2;
    }
}
