I suggest you write to the FreeType list.  It's either their bug (that
they will fix) or a bug in some library in how it uses FreeType (in
which case they will help you identify it).

(Re your other question, that is, disabling certain glyphs in certain
fonts, there's been patches proposed for it to this list before, but
it's not in fontconfig yet.)
