Hello. For chicken 4.9.0.1, it looks like this may have been an upstream bug. Looking at some of Recardo Wurmus's notes for some tweaks to chicken back then: https://lists.gnu.org/archive/html/chicken-hackers/2015-04/msg00063.html Seems to line up with a some chicken bugs reported back then: https://bugs.call-cc.org/ticket/1120 https://bugs.call-cc.org/ticket/1098 (and have been addressed upstream)
It has been a while and chicken scheme is now at 5.2.0 It is currently building on cuirass: https://ci.guix.gnu.org/build/2339572/details I am also able to build it locally: ----- $ guix --version guix (GNU Guix) 2971ed57345ee4e00058efeaf27c6a0790fdc9dd $ guix build chicken --no-substitute ----- Going to go ahead and close.
