Out of bounds panic

[HalfVoxel]

I don't know which file caused this, but in our server logs we found this out of bounds panic from sniffer:

thread 'tokio-runtime-worker' panicked at /root/.cargo/registry/src/index.crates.io-6f17d22bba15001f/csv-sniffer-0.3.1/src/sniffer.rs:282:54:

I hope the stack trace is helpful enough to figure it out.
