contract violation on 8.2[cs]?

[emacsomancer]

On v8.2 [cs], I seem to get an error when I try to launch rash (via racket -l rash/repl --):

Ooo, I don't always stay up to date on my Racket installation. Thanks for letting me know. I'll probably look at this on Monday.

No worries, and no rush. I look in on Rash from time to time and noticed this.

Now that I'm really looking at this, the context for the error is in the readline-lib package. (Along with about half of my other issues...) What OS are you using? I just fired up a fresh 8.2cs install and starting the rash repl doesn't raise any exceptions. That said, I also got an email recently about readline/libedit issues on Windows.

If you add --readline false does the problem go away?

I just need to write my new line editor... but when will I have the time?

The error is on an Arch Linux machine. (On a Void Linux machine running 8.0[cs], rash runs without issue.) The error indeed goes away on the Arch box if I run with --readline false.

And you don't get any error when you just run the Racket repl (which has readline enabled by default)?

The Racket repl itself seems to behave fine:

$ racket
Welcome to Racket v8.2 [cs].
> (print "hello world")
"hello world"
> (exit)

$ racket -l rash/repl --

You can use the `help` line macro to get help about topics.
(To turn these hints off, run (current-repl-display-startup-hints? #f) in a rashrc file.)
