Thanks, that was very useful. I don't think it really is a bug. But it is use
of undefined data. The issue is that if the ELF data structures need to be
converted then it only makes sense to convert full datastructures. But just
dropping the bad/partial data is not a great idea either. So this proposed
patch just copies over the bad/partial data that couldn't be converted. That
way it is at least deterministically defined.
