 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);
   }
 ---------------------------------------
