Internal compiler error

Thanks for your bug report. Although this is certainly a bug in the
compiler, I believe this is also a bug in your code.

> template<class key,class value>
> template<class key2,class value2>
> ostream& operator<<(ostream& ls, const Pair<key2,value2>& rs)
> {

The template arguments key and value are not needed, are they? If you
remove the first line, g++ compiles your code just fine.
