Given that John said that compilation went fine with
GUILE_JIT_THRESHOLD=-1, I think perhaps this problem may have been fixed
in the past.  My suspicions are that this issue is an ABI issue with
lightening that could perhaps be reproduced by:

  git co https://gitlab.com/wingo/lightening
  cd lightening
  make -C tests test-native

Of course any additional confirmation is useful and welcome!
