My pleasure!

In fact I already tried that (after having battled for a couple of days with
various typos and glitches in the distributed code, as per pme warning!)
And my *preliminary* results for main.cc (it includes and tests everything)
are not very good, indeed (session transcript follows):

However, please consider this as strictly *preliminary* (however, the seg
fault is *real* :(.
I'm planning to carefully "correct" the code again starting from the
distributed version and cross checking with you all any dubious
modification.
Only then file a GNATS PR, which, I hope, should also hint to the most
critical Loki libraries.
