It does. Take for example:

struct A {
  int q;
  int w;
  /* end of common part */

  float x;
};

struct B {
  int q;
  int w;
  /* end of common part */

  double x;
};

What if the C standard allows the compiler to place q and w further
apart in struct A than in struct B? Then if you cast struct A *a into
struct B *b, you'll get garbage in b->w.
