Subject: [ruby-core:30864] [Bug #2718] DRb mixing up function return values between PIDs after fork()

Issue #2718 has been updated by Sean Bradly.


I just verified that this shows up for me in Ruby 1.8.7-p249 as well as 1.9.1-p378. It does seem to reproduce a lot more readily in 1.8, however. 

Note that you must run the test script with at least one argument (the arg can be anything) to trigger the problem. With 0 arguments it skips the bug to show the known good case.
