Thanks for your response. My apologies for the empty subject. I hit
send before realizing I forgot to write one.

Unfortunately it is not my application, but a tool required to build
the Linux kernel. I have written a patch[0] which fixes the issue,
and I can try to submit it upstream.
I agree that the sanity check is good in general, but I have to
wonder if it makes sense to fail if the section type is just not
yet set (SHT_NULL), since that does not necessarily indicate an
application error.
