Comment 2 Jakub Jelinek 2001-11-07 13:05:03 EST

It is ICE on wrong code, you're missing a typename there.
Anyway, the compiler shouldn't segfault, but give an error, so I'll try to debug
this.
Simplified testcase is:
template <class T> struct S {
  typedef typename T::t t;
};
template <class T> struct A
{
  typedef S<T>::t u;
  typedef u::t v;
};

Comment 3 Alan Cox 2002-12-15 13:07:00 EST

Still present in g++ 3.2

Comment 4 Richard Henderson 2004-10-01 20:47:37 EDT

ICE fixed for gcc 3.4.
