I'm seeing an "invalid memory reference. Some debugging context lost" error when using a parameter that has a guard function AND the guard function is user-defined AND the guard function has a contract on it. What is the right place to file this aside from the list?
Demonstration: #lang racket/base (require racket/contract) (define p1 (make-parameter "")) (displayln "before set p1") (p1 "ok") (displayln "before read p1") (p1) (define/contract p2 (parameter/c string?) (make-parameter "")) (displayln "before set p2") (p2 "ok") (displayln "before read p2") (p2) (define/contract p3 (parameter/c string? integer?) (make-parameter "7" string->number )) (displayln "before set p3") (p3 "8") (displayln "before read p3") (p3) (define (uncontracted-string->number v) (string->number v)) (define/contract (contracted-string->number v) (-> string? number?) (string->number v)) (define/contract p4 (parameter/c string? integer?) (make-parameter "7" uncontracted-string->number)) (displayln "before set p4") (p4 "8") (displayln "before read p4") (p4) (define/contract p5 (parameter/c string? integer?) (make-parameter "7" contracted-string->number)) (displayln "before set p5") (p5 "8") (displayln "before read p5") (p5) ; invalid memory reference.
