C++ code works on gcc 4.4 but doesn't compile on 4.5.1

I'm trying to make a little testcase without std lib dependencies, but
I cannot reproduce the bug without it.

Here the code:

If you uncomment the two commented lines (adding the std code), the
error shows, but using my fake list class, the error dosn't occur.

Can you give me a point? or its better to report with std dependencies?

Thanks again.
Hugo.
