I think I found a false negative with this where if the member is accessed from 
a packed struct type returned from a function, the warning does not appear:

  typedef struct {
    uint8_t a;
    uint32_t b; 
  } __attribute__((packed)) registers_t;
  
  registers_t *Class::method() { return registers_; }
  
  void Class::func() {
    other_func(&method()->b);  // I think the warning should appear here?
  }
