("Clozure Common Lisp" "Version 1.11.5/v1.11.5 (LinuxX8664)")

(cl:pushnew :cl-opengl-no-masked-traps cl:*features*) solves the problem, but another small gotcha is that one would need to also manually trigger recompilation of cl-opengl by touching cl-openg.asd or other means (clearing caches, forcing with asdf).

Apparently, it was fixed in :float-features but didn't make it to quicklisp dist yet.
