Package: g++-4.4
Version: 4.4.2-9
Severity: normal

I did report a regression upstream, which ended up in
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43101 .  As requested in
README.Bugs I'm now reporting it here.

The following valid code is accepted by g++-4.3 but rejected by g++-4.4:
======================================================================
template <int dim> class X {};

template <class T> class Y {
    static const unsigned int dim = 1;
    X<Y<T>::dim> f();
};

template <class T>
X<Y<T>::dim> Y<T>::f() { return X<dim>(); }
======================================================================

There is a workaround, but it is quite difficult to find since several
variants don't work due to the ancient bug
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26261 .  The workaround is to
make a typedef for the return type and use that:
======================================================================
template <int dim> class X {};

template <class T> class Y {
  static const unsigned int dim = 1;
  typedef X<dim> Z;
  Z f();
};

template <class T>
typename Y<T>::Z Y<T>::f() { return X<dim>(); }
======================================================================

Thanks,
Jö.
