' ---------------------------------------- Bug #6634: Deadlock with join and ConditionVariable https://bugs.ruby-lang.org/issues/6634#change-27415 Author: meh. (meh. I don't care) Status: Open Priority: Normal Assignee: Category: core Target version: ruby -v: ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux] I'm getting a fatal deadlock in one of my gems, it's a simple threadpool implementation. The library works both in Rubinius and JRuby, so I guess it's a bug. The gem is here: https://github.com/meh/ruby-threadpool The example that crashes is attached. Basically it raises a fatal deadlock if you join a thread and then call ConditionVariable#wait, I'm not 100% sure if the bug is in the ConditionVariable or what, all I know is that it happens in that situation and that it works on Rubinius and JRuby. -- http://bugs.ruby-lang.org/
