Malformed r6rs program crashes drracket.
Could not reproduce this bug on Ubuntu, neither with an in-place install on Arch install with the official linux installer (.sh).
A reinstall of the package does not fix the issue.

Additional info:
* racket version 6.12-1

Steps to reproduce:
Open drracket, set language to 'racket' and paste the following:

#lang r6rs
(import (rnrs base))
(define test (lambda ()))

Alternatively, save this as anything.rkt and try to open it with drracket.
The result is the same.

Can reproduce. Interesting that it gives a SIGSEGV MAPERR with drracket and a trace with racket-minimal.

However this doesn't seem to be a new error. Our 6.11 package does the same thing.

If you'd like to help further debug, here are old versions:

I am by no means an expert with the internals of Racket, please continue investigating if you can.

Yeah, I should have mentioned that I first came across it on 6.11.

It's a pretty weird thing. I'm guessing it's just some module it can't find.
I'll diff the install from the official installer and the package sometime and get back to you with the results.
