That's exactly what `FALLTHROUGH ();' on the line above is supposed to
do:
https://git.savannah.gnu.org/cgit/mit-scheme.git/tree/src/microcode/interp.c?id=43ea2feb108135921eea80228c9797e95676209e#n830
Maybe the definition of FALLTHROUGH and ATTRIBUTE in confshared.h
isn't getting picked up by clang? Can you determine which branches of
those #ifs are getting hit on your system and why?
