Navigate into `main.rs` file via NerdTree 6. Replace the `main.rs` content with: ``` use fst::{Set}; use fst::automaton::Levenshtein; fn main() -> Result<(), Box> { let keys =3D vec!["hej"]; let set =3D Set::from_iter(keys)?; let lev =3D Levenshtein::new("foo", 1)?; println!("{:#?}", set); println!("{:#?}", lev); Ok(()) ``` 7. `:w` in neovim 8. `:! cargo build` in neovim (note that bash is in project's root folder w= hile neovim is simultaneously in `main.rs` at this point) 9. Open another terminal in project's root folder 10. In the new terminal, run `gdb target/debug/playground` (alternatively: `rust-gdb target/debug/playground`) 11. In gdb, run the following commands, one line at a time (note that I have [GDB Dashboard](https://github.com/cyrus-and/gdb-dashboard) implemented int= o my GDB): ``` list b 8=20 b 10 list b 11 b 12 r c ``` It crashes as soon as you enter `c`. The following specified what "crash" m= eans and shows the output that I see: ``` Breakpoint 2, playground::main () at src/main.rs:10 10 println!("{:#?}", set); ../../gdb/gdbtypes.h:1064: internal-error: field: Assertion `idx >=3D 0 && = idx < num_fields ()' failed.
