For the sake of experiment, trying to rebuild ngspice with options=(!strip) in PKBUILD I wonder, could it be the culprit? Any chance you could try this as well?

I tried building without strip and it looks the same:

So weird. Tried rebuilding with yet another addition of export LDFLAGS="${LDFLAGS/-Wl,--as-needed/}" (remove default -as-needed listed in /etc/makepkg.conf)

Perhaps I will cross-check debian packaging.

Well, both, Debian and Ubuntu package older versions of ngspice (and KiCad). And they do not ship shared objects. Only *.cm files. Which do export CMdecNum. And for that matter probably need someone from upstream, to understand how the heck is it supposed to load.
