Yes, that would happen when your system is little-endian. (According to 
spec, the length field is big-endian.)

You can detect what endianness the system has and swap the bytes of the 
length field:

   http://ddili.org/ders/d.en/union.html#ix_union.endian,%20std.system

import std.system;
import core.bitop;

// ...

     if (endian == Endian.littleEndian) {
         address.value = bswap(address.value);
     }

std.bitmanip may be useful as well:
