With less steps:

curl https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/3705d47bb3f3229234cba992320eadc97a221caf/plugins/rust/_rust > /path/in/fpath/_rust
autoload -Uz _rust; compdef _rust rustc
rustc --pretty flowgraph==<^I>

The interesting parts of _complete_debug

There are a few other places where the control characters show up but i am not sure what is creating it.
I can get zsh to crash by adding a space before _values on line 52 of the completer.
