And while at it how about s/g_malloc/gmalloc0? This would possibly make
something like mismatch in .start between source and target easier to
detect, along with the 'untouched' fields mentioned by Jianjun.
(Although I'm not sure how untouched fields and the virtio list use is
connected. In my understanding the problem pointed out by Juan has
something to do with the address of a element/node having significance
beyond the list.)
