  Type1* zone1 = reinterpret_cast<Type1*>(memory_block[0]);
  zone1->offset = 20;

  Type1* zone2 = reinterpret_cast<Type1*>(memory_block[20]);
  zone2->offset = 2 * 20;

  Type3* pageToUse = reinterpret_cast<Type3*>(memory_block[20]);


You are violating C++ aliasing rules. reinterpret_cast is still a normal cast.
