From this piece of code
----------------------------------------
#include <boost/intrusive/slist.hpp>

class Node : public boost::intrusive::slist_base_hook<> {
public:
  Node(int x) : x(x) {}
  int x;
};

typedef boost::intrusive::slist<Node> List;

int main(int argc,char *argv[]) {
  List list;
  Node n1(1234);
  Node n2(5678);
  list.push_front(n1);
  list.push_back(n2);
  return 0;
}
------------------------------------------
I get the following error:

johannes_at_pc1:~/Progs/Components/Boost> g++ IntrusiveTest1.C

This is boost_1_39_0. I use operating system

johannes_at_pc1:~/Progs/Components/Boost> uname -a
Linux pc1 2.6.22.19 #1 PREEMPT Fri Apr 10 00:41:29 CEST 2009 x86_64 AMD

and compiler gcc version 4.3.2 (Gentoo 4.3.2-r3 p1.6, pie-10.1.5)

I cannot understand, why list.push_front(n1) compiles, while
list.push_back(n2) fails to compile.

Thanks in advance for your help.

Yours,
