I have not able to create a minimum test case without Rails yet. ### Steps to reproduce ```ruby git clone https://github.com/rails/rails cd rails/actionview bin/test test/template/template_test.rb:278 ``` ### Expected behavior It should pass as it Runs parser.y parser ```ruby $ RUBYOPT=--parser=parse.y bin/test test/template/template_test.rb:278 /home/yahonda/.gem/ruby/3.4.0+0/gems/json-2.7.1/lib/json/common.rb:3: warning: ostruct was loaded from the standard library, but will no longer be part of the default gems starting from Ruby 3.5.0. You can add ostruct to your Gemfile or gemspec to silence this warning. Running 36 tests in a single process (parallelization threshold is 50) Run options: --seed 61197 # Running: .
