[racket-dev] Is anybody else getting this error?

I saw an error like this a few days ago, but it was in a large
project. This is the minimal example to reproduce the error.

I guest that the problem is that a .zo exist for an older version of a
file that now doesn't compile. The error disappears if I delete all
the .zo files.

I am using the DrRacket version 5.2.1 for Windows.

I filled a bug report with the information:
http://bugs.racket-lang.org/query/?cmd=view&pr=12590

Steps to reproduce the error:

1) Create two directories "\dir" and "\dir\subdir" with the files:
;--FILE: dir\def-one.rkt
#lang racket/base
(provide (all-defined-out))
(define (one) 1
#;(define (one) 1) ;duplicated

;--FILE: dir\subsir\one.rkt
#lang racket/base
(require "../def-one.rkt")
(one)

2) Add a "compile.ss" files to each directory
;--FILE: dir\compile.ss
#lang racket/base
(require compiler/compiler)
(require setup/getinfo)
(compile-directory-zos (current-directory)
                       (get-info/full (current-directory)))

;--FILE: dir\subdir\compile.ss
#lang racket/base
(require compiler/compiler)
(require setup/getinfo)
(compile-directory-zos (current-directory)
                       (get-info/full (current-directory)))

3) Run the "dir\compile.ss" to compile and create the .zo files

4) Edit the file "dir\def-one.rkt". Remove the #; so the definition of
"one" is duplicated, and save the file.

5) Run the other "dir\subdir\compile.ss" to compile and create the .zo
files only in the subdir.

6) Get the ERROR: exception raised by error display handler:
normalize-path: #<path:C:/var> (within the input path) is not a
directory or does not exist; original exception raised: module:
duplicate definition for identifier

To repeat:

+7) Edit "dir\def-one.rkt" to make it a valid file. Add again the #; and save

+8) Run "dir\compile.ss" to compile everithing.

+9) Edit "dir\def-one.rkt" to make it a invalid. Remove the #; or add
or remove a random ( or ).

+10) Run again "dir\subdir\compile.ss" to get the error.
