Issue #21547 has been updated by Earlopain (Earlopain _). File crash.log added I reproduces pretty much all the time for me (with a clean install). A good starting point seems to be the `cool.io` gem (https://github.com/socketry/cool.io/), running its specs with `bundle exec rspec spec/tcp_server_spec.rb:111` also crashses. ``` -- C level
