[ruby-core:111409] [Ruby master Bug#19254] Enabling YJIT configuration option breaks rspec-core test suite

Issue #19254 has been updated by k0kubun (Takashi Kokubun).

Status changed from Open to Feedback

In addition to @mame 's point, can you report how to reproduce the issue by building Ruby from a source or a tarball? e.g.

```
$ git clone --depth=1 https://github.com/ruby/ruby
$ cd ruby
$ ./autogen.sh
$ ./configure --enable-yjit --prefix="/opt/rubies/ruby" && make -j8 && make install

$ git clone --depth=1 https://github.com/rspec/rspec-core
$ cd rspec-core
$ unset GEM_ROOT GEM_HOME GEM_PATH
$ export PATH="/opt/rubies/ruby/bin:${PATH}"
$ bundle install
$ bundle exec rspec spec/rspec/core/example_spec.rb
```

And it doesn't reproduce any problem.


```
$ cd rspec-core
$ git rev-parse HEAD
522b7727d02d9648c090b56fa68bbdc18a21c04d
$ ruby -v -e "p RbConfig::CONFIG['YJIT_SUPPORT']"

* Author: vo.x (Vit Ondruch)
* Status: Feedback
* Priority: Normal
* ruby -v: ruby 3.2.0dev (2022-12-23 master c5eefb7f37) [x86_64-linux]

----------------------------------------
In preparation for Ruby 3.2, we have enabled YJIT in Fedora:

https://src.fedoraproject.org/rpms/ruby/c/3c1be9f9c2c1d8679eebb9a185fefa15baa1bcfc?branch=private-ruby-3.2

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.
