And from the documentation:

The returned value is a pointer to a temporary buffer owned by the receiver.
The buffer goes away with the unarchiver, not the containing autorelease pool.
You must copy the bytes into your own buffer if you need the data to persist
beyond the life of the receiver.
So if your setContinuationSize: allocates memory, you should:
const uint8_t *bytes = [aDecoder decodeBytesForKey:@"continuations"
returnedLength:&size];
NSAssert(size == [self continuationsSize] * sizeof(float), @"Bad size
of bytes returned from decoding");
memcpy(continuations, bytes, size);
