I use class allocated slots all the time. The way to set them in
define-class is with the :initform slot option. Here's an example:

(define-class <Whatever> ()
  [(shared-counter :allocation :class :initform 0)])

Although I've used a simple initial value here (0), I could put arbitrary
complex expression after the :initform keyword.

Good luck.
