I can't compress the testcase much more:
------------------------------
struct x {
    int foo () {}
};

template <class T>
struct vector {
    T& bar () {}
};

template <class T>
struct y {
    typedef struct {   
        x t;
    } s;
    
    vector<s> array;

    int foo ()
      { return array.bar().t.foo(); }
};
int i = y<x>().foo ();
------------------------------------
The most interesting observation is probably that if I replace the
  typedef struct {...} s;
stuff with simply
  struct s {...};
then the ICE goes away. So maybe it has to do with a bad interaction of
templates and anonymous struct.s
