Issue #21454 has been updated by nobu (Nobuyoshi Nakada). Use no-dbg.rb with `RUBYOPT=-rno-dbg` when you run without `rdbg`. ```ruby class Binding def break = nil end ``` ---------------------------------------- Feature #21454: "undefined method 'break' for an instance of Binding" https://bugs.ruby-lang.org/issues/21454#change-113992 * Author: vo.x (Vit Ondruch) * Status: Open ---------------------------------------- Running my code with `rdbg` and using `binding.break`, it is a bit unfortunate that subsequently running the code without `rdbg`, it fails with error such as: ~~~ NoMethodError: undefined method 'break' for an instance of Binding ~~~ Could this method become no-op if the `rdbg` is not loaded? If there was some concern about this, then it could print some helpful warning or what not. -- https://bugs.ruby-lang.org/
