racket

[Benjamin Slade]

When run Racket, in the REPL, the first command I execute runs fine. But
the second (no matter what it is, even if it's just the first again)
always produces:

; ptr-ref: contract violation
;   expected: (and/c cpointer? (not/c (lambda (p) (pointer-equal? p #f))))
;   given: #f
;   argument position: 1st
; [,bt for context]
; ptr-ref: contract violation
;   expected: (and/c cpointer? (not/c (lambda (p) (pointer-equal? p #f))))
;   given: #f
;   argument position: 1st
; [,bt for context]

And it doesn't accept any more input after that point (including ",bt").
