Rails - Nov 2004 - Stack level too deep on Cygwin and on Debian / Colinux with 0.5.0 - 0.8.5 Beta gems

Hi,

as it is not possible for me to use a sensible development environment 
to start with I have to use emulations. I use Cygwin on windows and also 
Colinux. (Colinux is really amazing cause it lets you run actual linux 
binaries und Windows.) So here is my problem, which by the way exists 
since Rails 0.5.0 I think. It was the reason I tried Colinux in the 
first place, cause the error first appeared on Cygwin. So here goes:


1) First the the way how to get there.

$ rails stackleveltest
$ cd stackleveltest
$ ruby script/new_controller Stacktest

# edit app/controllers/stacktest_controller.rb to look like:
-----
require ''abstract_application''

class StacktestController < AbstractApplicationController
   helper :stacktest
   def test; end
end
-----

edit app/views/stacktest/test.rhtml to look like:
-----
<% check_box "password", "secret" %>
-----

$ ruby public/dispatch.servlet -p 4000 -b debian
$ links http://debian:4000/stacktest/test

gives:

2) Second with a unit test

I am uncertain how to best show this with a unit test. Here is my 
attempt, which is to simply process the :test action.

edit file test/functional/stacktest_controller_test.rb to read:
-----
require File.dirname(__FILE__) + ''/../test_helper''
require ''stacktest_controller''

# Re-raise errors caught by the controller.
class StacktestController; def rescue_action(e) raise e end; end

class StacktestControllerTest < Test::Unit::TestCase
   def setup
     @controller = StacktestController.new
     @request = ActionController::TestRequest.new
     @response = ActionController::TestResponse.new
   end

   def test_test
     process :test
     #assert_success
     #assert_rendered_file ''test''
   end
end
-----

CONCLUSION
I don''t know if it is my machine or if it has something to do with 
Cygwin or Colinux. If anyone happens to have a similiar setup I would be 
glad to be confirmed. If there is anything else I can do to help with 
this bug, pls let me know.
