We had offline discussions with Nuno about his code whose portions
I paste below (with his permission):

void
PREQDestination::Serialize (Buffer::Iterator start) const
{
  Buffer::Iterator i = start;
  WriteTo (i, m_destinationaddress);
}

void 
PREQPerDestinationFlags::Serialize (Buffer::Iterator start) const
{
  Buffer::Iterator i = start;
  i.WriteU8 (m_value);
}

class PREQInformation : public Header;

void 
PREQInformation::Serialize (Buffer::Iterator start) const
{
  Buffer::Iterator i = start;
  while (j != m_destinationcount)
  {
   m_perdestinationflags[j].Serialize (i);
   m_destination[j].Serialize (i);
   j++;
  }

}

His problem stemmed from passing iterator parameters by value before
serializing arrays elements :
- Buffer::Iterator i = start,
- PREQPerDestinationFlags::Serialize (Buffer::Iterator start)
- PREQDestination::Serialize (Buffer::Iterator start)

Passing iterator parameters by reference in PREQPerDestinationFlags and
PREQDestination Serialize (...) fixed his problem indeed.
