# Remote Debugger Failure
This repository is a minimal proof of concept which causes ruby-debug to behave erratically when debugging a remote process.
## Reproduction Steps
1. Clone this repository
2. `bundle install`
3. `./run`
4. visit [localhost:3000](http://localhost:3000)
5. Attach to the remote debugger wiht `rdbg --attach`
## Faulty behavior
```consolesession
> rdbg --attach
