A few days ago, after migration on 3.3.0 I have faced with issue inside subexpression calls. An expected result on Ruby up to 3.3.0: ```ruby '1.2.3'[/(\d+)(\.\g<1>){2}/] # => "1.2.3" ``` An actual result on Ruby 3.3.0: ```ruby '1.2.3'[/(\d+)(\.\g<1>){2}/] # => nil ``` -- https://bugs.ruby-lang.org/
