[ruby-core:118865] [Ruby master Bug#20679] Rails CI errors since abc04e898b627ab37fa9dd5e330f239768778d8b

[jeremyevans0 (Jeremy Evans) via ruby-core]

Issue #20679 has been updated by jeremyevans0 (Jeremy Evans).


Reverted in commit:d56470a27c5a8a2e7aee7a76cea445c2d29c0c59

Here's a failing example that does not require Rails:

```ruby
class A
   def self.get(uri, params = {}, env = {}, &block)
     env['HTTPS']
   end

  ruby2_keywords def get(*args, &block)
    A.get(*args, &block)
  end
end

A.new.get("/pages/foo", {}, "HTTPS" => "on")

```

Definitely related to the `ruby2_keywords` optimization. I'll keep digging to find the root cause. I'll leave this open until I have a working fix.

Rails hits this through use of forwardable in rack-test. We should also consider switching forwardable to use generic argument forwarding (`...`) instead of `ruby2_keywords` when using Ruby 2.7+.  It's simpler, and faster on Ruby 3.4 as generic argument forwarding is now allocationless.

[jeremyevans0 (Jeremy Evans) via ruby-core]

Issue #20679 has been updated by jeremyevans0 (Jeremy Evans).

I submitted a pull request for the fix: https://github.com/ruby/ruby/pull/11409

Root cause was when I extracted a function, I missed the use of a local variable after the extraction.  This wasn't caught because the same variable existed in a higher scope.
