Starting from r246756 we ICE on:

$ cat Buffer.ii
class a
{
  char b;
  void c ();
};
void
a::c ()
{
  &b + ((long long) &b & 0);
}

$ g++ Buffer.ii -O2 -m32 -c
Buffer.ii: In member function ‘void a::c()’:
Buffer.ii:9:27: internal compiler error: tree check: expected boolean_type or
enumeral_type or integer_type, have pointer_type in do_narrow, at convert.c:474
   &b + ((long long) &b & 0);
