> Hmmm, I probably forgot to run `make test` (which rebuilds `test/test`
with a ''debug version'' of `src/tuning.c`) in addition to `make` (which
apparently just rebuilds the static library, not used by `test`; IMHO a
flaw in the Makefiles).

Ooops, not true. In the last attempt, I missed that `nuss_mul()` failed,
but only when tested "extensively":

Presumably because those tests take a pretty long time... ;-)
