 Ack, somehow gnats only picked up my name change, but not the analysis:
 
 Confirmed with both 3.2.1pre and CVS. The infinite loop 
 appears in cp/decl2.c(finish_file), in the 
 do...while(reconsider) loop. "reconsider" is continuously 
 re-set to 1 in line 3512 (in the 3.2.1 branch).
 
 A smaller, self-contained example is this:
 --------------------------------
 struct Outer {
     struct Inner { virtual bool f() = 0; };
     void g(Inner &) const;
 };
 
 
 inline void h(const Outer &o)
 {
   struct Local : public Outer::Inner {
       virtual bool f() {};
   };
   Local l;
   o.g(l);
 }
 
 
 void f(Outer &req) {
   h (req);
 }
