Re: c++/2703: Internal error #20000409 for g++-3.0 (20010423)

I narrowed this one down a bit, the problem is applying typeof() on
a variable that has a template parameter as type, ie:

O well, this test case gives a different error :/, but thats the problem anyway.
test.cc in this case reads:

---------------------------------------
template<typename T>
  void f(T* x)
  {
    typeof(x);
  }
---------------------------------------
