I don't know, but from the message it looks like some 'local' variables
is not saved and defined. I'm surprised that loading some mf file works
at all (because it also assumes some mf related definitions). I also
hav
eno clue if such a package adopts 'core' metafun code (and mpiv metafun
is different from mpii).
It's a generic, "pure" MetaPost package:
https://www.ctan.org/pkg/cmarrows <https://www.ctan.org/pkg/cmarrows>
that doesn't make it immune from clashes in used variables with differnt
types ... metafun is more than plain mp so more can clash
Fonts are in /fonts/source/public in a TeX Live distribution, in case it
helps.
i have a rather minimal tex setup so i can't run that (i'm not going to
clutter my system now)
