Issue #19254 has been reported by vo.x (Vit Ondruch). ---------------------------------------- Bug #19254: Enabling YJIT configuration option breaks rspec-core test suite https://bugs.ruby-lang.org/issues/19254 * Author: vo.x (Vit Ondruch) * Status: Open * Priority: Normal * ruby -v: ruby 3.2.0dev (2022-12-23 master c5eefb7f37) [x86_64-linux] * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN ---------------------------------------- In preparation for Ruby 3.2, we have enabled YJIT in Fedora: https://src.fedoraproject.org/rpms/ruby/c/3c1be9f9c2c1d8679eebb9a185fefa15ba... Since that moment, rspec-core test suite started to fail (see the attached log for all details): ~~~ ... snip ... 1) RSpec::Core::Example#run memory leaks, see GH-321, GH-1921 releases references to the examples / their ivars Failure/Error: expect(get_all.call).to eq opts.fetch(:post_gc) expected: [] got: ["after_all", "before_all"] (compared using ==) # ./spec/rspec/core/example_spec.rb:469:in `expect_gc' # ./spec/rspec/core/example_spec.rb:492:in `block (4 levels) in <top (required)>' # ./spec/support/sandboxing.rb:16:in `block (3 levels) in <top (required)>' # ./spec/support/sandboxing.rb:7:in `block (2 levels) in <top (required)>' Finished in 8.98 seconds (files took 0.47612 seconds to load) 2209 examples, 1 failure, 4 pending ~~~ Please note that the YJIT was not enabled during runtime, just the support was enabled. Disabling the YJIT supports makes the test case pass. [1]: https://download.copr.fedorainfracloud.org/results/vondruch/ruby-3.2/fedora-...
