I am using MRI 1.9.3, Rails 3.2.1, spork 0.9.0, test-unit 2.4.5, and spork-testunit. Regardless of whether I use spork-testunit 0.0.7 or the latest git master, I get this 'recycled object' error from bundle exec testdrb:

Error executing -Itest ./test/functional/admin/assignments_controller_test.rb ./test/functional/admin/availabilities_controller_test.rb ./test/functional/admin/events_controller_test.rb ./test/functional/admin/people_controller_test.rb ./test/functional/admin/roles_controller_test.rb ./test/functional/events_controller_test.rb ./test/functional/people_controller_test.rb ./test/functional/replies_controller_test.rb ./test/functional/routes_test.rb ./test/functional/sessions_controller_test.rb

------------------------------
Done.

I experimented with trimming the list of tests run, and found that it is triggered by any test which has an error (not a failure). When triggered, one of two things happen: (1) the above stack trace, or (2) what should be the summary line in the output (e.g. something like 20 tests, 106 assertions, 0 failures, 0 errors, 0 pendings, 0 omissions, 0 notifications) actually ends up being complete garbage, e.g.

$ bundle exec testdrb -Itest ./test/functional/admin/roles_controller_test.rb

0% passed

3.09 tests/s, 11.31 assertions/s

So it looks to me like some memory pointer has gone AWOL and this string just gets plucked from a random memory area. Ouch!

Given that it is the summary line which goes FUBAR, I strongly suspect that this is related to issue #33. However, this happens even after I manually edited testdrb to prevent it getting confused by the presence of the minitest gem.

This is the final straw for me. I've had endless woes trying to get Spork and Guard to play nice with both test-unit and minitest, so I'm going to switch to RSpec which is hopefully a more well-trodden and reliable path.

I'm getting this same error on Ruby 1.9.3, Rails 3.2.3, spork (1.0.0rc3), spork-testunit (0.0.8). Both spork libs via git.

Has anyone figured out a solution for this?

I notice that drb is running out of RVM_PATH/lib/ruby/1.9.1 but I am using ruby 1.9.3. Maybe that is part of the issue?
