Difftastic panics when diffing two YAML files

Small repro with 2 YAML files, no git involved. I have the current Homebrew build.

https://github.com/Wilfred/difftastic/issues/702 seems similar but I'm not using --display inline nor git diff

#!/usr/bin/env bash

cat >og.yml <<EOF
name: Break it all
jobs:
    steps:
        run: |
          set -x
          git clone  https://github.com/torvalds/linux
EOF

cat >changed.yml <<EOF
name: Break it all
jobs:
    steps:
        run: |
          git clone  https://github.com/torvalds/linux
EOF

RUST_BACKTRACE=full difft og.yml changed.yml
difft --version

My output
