strange error message with debugging enabled

[Jos Koot]

file b.rkt

#lang racket
(require "a.rkt")
(err 5)

file a.rkt

#lang racket
(require "a.rkt")
(err 5)

Run file b.rkt from DrRacket.

Normal error message when debugging on file b.rkt is not enabled.

With debugging enabled:

-- #(struct:exn:fail:contract "vector-ref: contract violation\n  expected: vector?\n  given: ((error 'err \"blah blah ~s\" x) #<path:E:\\circuits\\delayed\\a.rkt> 3 16 44 29)\n  argument position: 1st\n  other arguments...:\n   0" #<continuation-mark-set>)
exception raised by error display handler: vector-ref: contract violation
  expected: vector?
  given: ((error 'err "blah blah ~s" x) #<path:E:\circuits\delayed\a.rkt> 3 16 44 29)
  argument position: 1st
  other arguments...:
   0; original exception raised: err: blah blah 5

Maybe this has already been posted as a racket issue.

Therefore I post this here.

If not yet an issue, I'll post a racket issue.

Thanks, Jos

Thanks, Jos. I think that this has been fixed (recently, since 7.8 was released). You might try a snapshot build and see if things are better for you there:

Thanks Robby.

Yes, it has been fixed. No problems in v7.8.0.10.
