Actually, these errors were intentional. The demo is not particularly
interesting as a runtime example. It is more interesting for developers
as an API example. Part of that example was to demonstrate that each
pointer argument is typecasted based on the length modifier and
conversion specifier associated with that argument.

Whenever I want to compile the demo program
(--with-minicoredumper_demo), I also add --without-werror. I _want_ to
see those warnings as it is proof for me that the automatic type
checking is working.

Perhaps I should modify main.c like this? Any thoughts?
