Hi Ben,

Good to head from you.

Taking a quick look at that code, the main issue compiling it with the
current ROTD is that the argument ordering of the predicates
set.insert/3 and map.det_insert/4 has changed in the interim.  More
signficantly, it appears to work by reading the HLDS dumps -- there's no
guarantee that the contents of those will have remained stable.

(The Mercury system itself, has a test coverage capability, which I
think could be used to replace a chunk of what is discussed in the
latter part of the linked paper.)
