Why have you closed the issue? Please, try to install perlbrew and use a perl from it, not the system one. Probably there is a problem with your system perl.

Debugger itself has no C extensions and should not cause a segfault. So this is a perl itself, or one of dependencies (some of them using XS)

Same thing on 9.2.19.0 ``` org/jruby/RubyModule.java:3766:in `const_missing' /home/user/.rbenv/versions/jruby-9.2.19.0/lib/ruby/stdlib/monitor.rb:233:in `mon_synchronize' ``` jruby-9.2.19.0: ver.9.2.19.0 (2.5.8) 55810c552b OpenJDK 64-Bit Server VM 11.0.11+9-Ubuntu-0ubuntu2.18.04 on 11.0.11+9-Ubuntu-0ubuntu2.18.04 +jit p0

Instability of this issue may indicate some race condition from my experience

Same on `jgem install rubocop` ``` warning: thread "Ruby-0-Thread-3: /home/user/.rubies/jruby-9.2.19.0/lib/ruby/stdlib/rubygems/request_set.rb:168" terminated with exception (report_on_exception is true): NameError: uninitialized constant Gem::Specification Did you mean?

Not sure if this one is the same, but may be the same cause (unstable reproduction, pretty rare) on `jgem install rubocop` ``` warning: thread "Ruby-0-Thread-3: /usr/share/rvm/rubies/jruby-9.2.19.0/lib/ruby/stdlib/rubygems/request_set.rb:168" terminated with exception...

You can't have access to our project, but there is nothing fancy going on in Specifications/Gem::Version case. Just running `bundle install` or `jgem install`. That's it. In bundler case, after...

One more.
