--- Comment #1 from Drea Pinski <pinskia at gcc dot gnu.org> ---

  char storage[64] __attribute__((aligned(8)));
  Entry* entry = reinterpret_cast<Entry*>(storage + 28);


This is undefined. Entry requires 8 byte alignment but you are not providing a
pointer which is not aligned correctly so what is happening is exactly what you
expect.
