------- Additional Comments From bangerth at dealii dot org  2003-07-09 14:18 -------
Yes, the code is invalid, and yes gcc versions 3.2, 3.3 and mainline
ICE on that (don't have older versions on this machine, sorry). Here's
a cut down testcase:
------------------------
template <typename T>
struct X {
  typedef typename T::type type;
};

template <typename T>
X<T>::type::type() {}
-------------------------

tmp/gg> c++ -c y.cc
y.cc:7: internal compiler error: Segmentation fault
