* dlang/dmd#5852 (fix Issue 15399 - unaligned pointers are not
  `@safe`) - triggered at line:
  https://github.com/kiith-sa/D-YAML/blob/v0.5.3/source/dyaml/emitter.d#L1011

* dlang/dmd#5940 (Unions may break immutability / unions with
  pointers are un-`@safe` ) - triggered at line:
  https://github.com/kiith-sa/D-YAML/blob/v0.5.3/source/dyaml/event.d#L230

* dlang/dmd#5876 (Casting from `void[]` to `T[]` is erroneously
  considered `@safe`) - triggered at line:
  https://github.com/kiith-sa/D-YAML/blob/v0.5.3/source/dyaml/loader.d#L186

* dlang/dmd#5860 (array.ptr in @safe code may point past end
