Hi Eljay!
I think the problem is in new auto_ptr, which differs from
previous releases.
The testcase works fine with gcc 3.2.
Here are my dependencies:

It also works with gcc 3.3.3 . Could you repost this in a forum like
comp.lang.c++.moderated, and start a discussion about whether or not
the code is well-formed?

Hi Lev,
Hmm, your code worked for me on GCC 3.3.1 under Cygwin / WinNT5.1sp1a. I
don't have 3.4.0 at my fingertips yet.
You are using GCC 3.4.0. Did your code work for you in previous versions
of GCC? Is it possible that you are using an outdated or incorrect version
of <memory>?

Hi all!
With auto_ptr from gcc 3.4 STL I can't create reference to auto_ptr.
autoptr.cpp:
#include <memory>
using namespace std;
auto_ptr<int> get() { auto_ptr<int> ai(new int); return ai;}
int main()
{
const auto_ptr<int>& rai = get();
}
Compilation:
/expor...ic_refer$>g++ -c autoptr.cpp
autoptr.cpp: In function `int main()':
autoptr.cpp:7: error: passing `const std::auto_ptr<int>' as `this' argument of `std::auto_ptr<_Tp>::operator std::auto_ptr_ref<_Tp1>()
[with _Tp1 = int, _Tp = int]' discards qualifiers
Is it a bug?
It used to work with gcc 3.2.
