I have the following module in abc/main.rkt:

#lang racket

(provide (all-defined-out))

(define (abc) 10)

Here's a short R6RS program which imports that module:

#!r6rs

(import (rnrs) (abc))

(display (abc))
(newline)

This error message appears at the bottom of the DrRacket window when that program is loaded:

+: contract violation expected: number? given: #f argument position: 1st other arguments...: 0

I'm able to run the program successfully however.

Any suggestions on how to get rid of the error?
