-strict-types fails with forall types (sometimes)

[Moritz Heidkamp]

(define-record bar foo)

(define-type bar
  (struct bar))

;; This breaks with csc -strict-types
(: foo (forall (x string) (x -> bar)))

;; Using this declaration instead of the above makes it work
;; (: foo (string -> bar))

;; Alternatively, removing this declaration makes it work, too
(: make-bar (string -> bar))

(define (foo x) (make-bar x))

Tested with 4.8.0rc2

Whoops, forgot to mention the actual error. It's

Error: [internal compiler error] resolve: can't resolve unknown type-variable: x20

        Call history:

        <syntax>          (##core#begin (define (foo x) (make-bar x)))
        <syntax>          (define (foo x) (make-bar x))
        <syntax>          (##core#set! foo (##core#lambda (x) (make-bar x)))
        <syntax>          (##core#lambda (x) (make-bar x))
        <syntax>          (##core#begin (make-bar x))
        <syntax>          (make-bar x)  <--
