[ruby-core:125518] [Ruby Bug#22072] [BUG] should have cvar cache entry
Issue #22072 has been reported by rmosolgo (Robert Mosolgo). ---------------------------------------- Bug #22072: [BUG] should have cvar cache entry https://bugs.ruby-lang.org/issues/22072 * Author: rmosolgo (Robert Mosolgo) * Status: Open * ruby -v: ruby 4.0.4 (2026-05-12 revision b89eb1bcbf) +PRISM [x86_64-linux] * Backport: 3.3: UNKNOWN, 3.4: UNKNOWN, 4.0: UNKNOWN ---------------------------------------- Hi! I have a CI build for my project that runs on Ruby 4.0.4, and it has recently started _sometimes_ segfaulting with this error: "". I have seen failures in two different spots: - In the middle of tests: ``` /home/runner/work/graphql-ruby/graphql-ruby/vendor/bundle/ruby/4.0.0/gems/liquid-4.0.4/lib/liquid/strainer.rb:43: [BUG] should have cvar cache entry ruby 4.0.4 (2026-05-12 revision b89eb1bcbf) +PRISM [x86_64-linux] ``` https://github.com/rmosolgo/graphql-ruby/actions/runs/25750012675/job/756235... - At the very beginning of the suite: ``` # Running tests with run options --seed 45415: /home/runner/work/graphql-ruby/graphql-ruby/spec/graphql/dataloader_spec.rb:1515: warning: Scheduler should implement #fiber_interrupt /home/runner/work/graphql-ruby/graphql-ruby/spec/graphql/schema/ractor_shareable_spec.rb:54: warning: Ractor API is experimental and may change in future versions of Ruby. /home/runner/work/graphql-ruby/graphql-ruby/vendor/bundle/ruby/4.0.0/gems/railties-8.1.3/lib/rails/generators.rb:27: [BUG] should have cvar cache entry ruby 4.0.4 (2026-05-12 revision b89eb1bcbf) +PRISM [x86_64-linux] ``` https://github.com/rmosolgo/graphql-ruby/actions/runs/25922299759/job/761942... I have attached the full crash messages to this issue. I don't have any guesses what to do next with these errors, but I thought I'd report them in case they're helpful. I'm happy to debug with my project if there's anything I can do to help. For now, I can get it to pass by re-running the build. Thanks!
