When compiled with -g the following reduced testcase causes an ICE (see output 
below), without -g everything is fine. I noticed report PR19163 which exposes 
other (unrelated?) __attribute__(aligned) problems. This is a 3.4 regression. 
 
This is with today's trunk, configured without options (except --prefix). 
  
template <typename T>  
struct BVector  
{  
  typedef T value_type __attribute__ ((aligned(8)));  
};  
BVector<int> m;  
  
  
jan@nbelvis$ g++ -c luinvert.ii  
jan@nbelvis$ g++ -g -c luinvert.ii  
luinvert.ii: In instantiation of ?BVector<int>?:  
luinvert.ii:6:   instantiated from here  
luinvert.ii:3: internal compiler error: in is_base_type, at dwarf2out.c:8058
