Is it a known issue ?

Maybe. Try the following perhaps:

(sb-int:with-float-traps-masked (:invalid :divide-by-zero) (rb-double))

Another detail: when gears or glut-teapot are running if I destroy the window (clicking on the cross), the lisp dies too. Is it supposed to to behave like this ?

Not at all. Someone else mentioned this problem in #lisp and was using FreeGLUT 2.2. IIRC, upgrading to version 2.4 fixed that.
