            Bug ID: 35724
           Summary: regression (r315984): fatal error: error in backend:
                    Broken function found (Did not see access type in
                    access path!)
           Product: clang
           Version: trunk
          Hardware: PC
                OS: All

The commit r315984 causes a backend crash in this code sample:

class a {
public:
  int b;
};
class c : public a {};
class d {
public:
  c f;
};

int fn1(d *e) { return (&(e->f))->b == 0; }

This is the crash:

Did not see access type in access path!
  %2 = load i32, i32* %b, align 4, !tbaa !7
!7 = !{!8, !10, i64 0}
fatal error: error in backend: Broken function found, compilation aborted!
