In principle okay, but I have a question first:

In these two you adjust (identical) conditions involving
"internal->sh_link > num". However, here ...

... it is "section->sh_link >= filedata->file_header.e_shnum". The latter
looks correct to me while the former doesn't until switched to also
using >= . While one could argue this is an unrelated change, imo it
would better be done while fiddling with this anyway. Thoughts?
