However, examples run without issue after declaring:

SBCL:

  (cl-glfw3-examples:basic-window-example))

I also encountered this problem in Debian using SBCL version 1.4.16:

michael@debian:~$ uname -a
Linux debian 4.19.0-10-amd64 #1 SMP Debian 4.19.132-1 (2020-07-24) x86_64 GNU/Linux

I just tested this in FreeBSD 12 running SBCL 2.0.3; the example works without giving any floating point errors.

I also updated SBCL in Debian to 2.0.7, but I'm still getting the same error above.
