i'm using racket textual v5.3.6 on windows. ~a seems to be crashing my sandboxed programs.
Here's an example (foo.rkt): #lang racket/base (require racket/sandbox) (define evaluate (make-evaluator 'racket '(define (main) (~a (+ 1 2))))) (evaluate '(main)) When I run foo.rkt at the prompt, I get an error: d:\test\racket foo.rkt current-directory: `exists' access denied for D:\test\ context...: C:\Program Files\Racket-Textual\collects\setup\private\main-collects.rkt:19:4: find-main-collects C:\Program Files\Racket-Textual\collects\racket\private\promise.rkt:104:10 C:\Program Files\Racket-Textual\collects\racket\private\more-scheme.rkt:263:2: call-with-exception-handler C:\Program Files\Racket-Textual\collects\racket\private\promise.rkt:96:0: force/generic C:\Program Files\Racket-Textual\collects\setup\path-relativize.rkt:31:4: exploded-root C:\Program Files\Racket-Textual\collects\racket\private\promise.rkt:104:10 C:\Program Files\Racket-Textual\collects\racket\private\more-scheme.rkt:263:2: call-with-exception-handler C:\Program Files\Racket-Textual\collects\racket\private\promise.rkt:96:0: force/generic C:\Program Files\Racket-Textual\collects\setup\path-relativize.rkt:34:2: path->relative C:\Program Files\Racket-Textual\collects\setup\path-to-relative.rkt:31:2: path->relative-string9 C:\Program Files\Racket-Textual\collects\racket\contract\private\provide.rkt:58:9 C:\Program Files\Racket-Textual\collects\racket\sandbox.rkt:631:18 C:\Program Files\Racket-Textual\collects\racket\sandbox.rkt:363:0: call-with-limits C:\Program Files\Racket-Textual\collects\racket\sandbox.rkt:611:0: evaluate-program C:\Program Files\Racket-Textual\collects\racket\private\more-scheme.rkt:146:2: call-with-break-parameterization C:\Program Files\Racket-Textual\collects\racket\sandbox.rkt:744:2: user-process I don't get an error when I remove the call to ~a. ____________________ Racket Users list: http://lists.racket-lang.org/users
