Thank you! Is it relevant today at all, or is there an use-case for it today?

  No, if you need fixed addresses i suppose a linker script would be the way to go? Or in this case you'd just serialize the data such that it doesn't contain any pointers in the first place.

    If you even can with ASLR. Most modern boxes would disable stuff like this.

  There are better tools to do this these days—with the GNU toolchain, for example, you’d use a linker script and make sure you’re building a non-position-independent static executable. Alternatively, you could use self-relative pointers: instead of having foo_t *foo and putting p there, have ptrdiff_t foo and put ((char *)p - (char *)&foo) there.
