  I know it is broken for Darwin/BSD since
https://git.savannah.gnu.org/cgit/lightning.git/commit/?id=38e20cebf6430f48ebcd1c8b608b3329abc0221a

  If it is Linux or AIX, it should work in the latest official
release. You might
experiment with a bisect from
https://git.savannah.gnu.org/cgit/lightning.git/commit/?id=e0383cb2de8eeaa30f86ae6c586740e8e93abbf6
to the latest commit, as some change might have broken it. What is quite
possible, as most tests pass.

  Apparently it is an issue with floating point registers.

Thanks!
Paulo
