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!
