Summary
The original summary included a lot of context that isn't related. After some discussion this is what has been found.
If you have a file with the following:
-1
-1
And you enter the following keystrokes:
% s - <enter> C-a
Helix panics.
This doesn't happen when there is a character, space or empty line after the two lines:
-1
-1
(Helix doesn't panic with the above input on this text)
Here is the backtrace with RUST_BACKTRACE=1:
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Char index out of bounds: char index 4, Rope/RopeSlice char length 3', /home/jm/.cargo/registry/src/g.yxqyang.asia-1ecc6299db9ec823/ropey-1.4.1/src/slice.rs:349:41

note: Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace.
I also now updated the Helix version to my now current version on this issue because this bug still exists at the time of writing.
