You are using CFFI 0.9.2, which is over ten years old. Try using a more recent CFFI, which is compatible with modern SBCL.

One thing to try first off -- quickload by default suppresses errors (catches them) and keeps you from getting at them. So you should do the (asdf:load-system :cffi) again, but this time get a backtrace. That will give people more information so that they can help.

I’m running Mojave 10.14.2 and SBCL 1.5.0. When I try to load CFFI, I get this error:

Then I’m dumped into the debugger. The same thing occurs using (asdf:load-system :cffi). I’ve cleared ~/.cache/common-lisp, but no joy. Any thoughts appreciated.

Thanks,
