Dandandan opened a new issue, #22221: URL: https://github.com/apache/datafusion/issues/22221
### Describe the bug `lead` panics during planning when given `i64::MIN` as the offset. The implementation negates lead offsets, and negating `i64::MIN` overflows. ### To Reproduce ```sql EXPLAIN SELECT lead(x, -9223372036854775808) OVER (ORDER BY x) FROM (VALUES (1)) AS t(x); ``` ### Actual behavior ```text thread 'main' panicked at .../library/core/src/ops/arith.rs: attempt to negate with overflow ``` ### Expected behavior Return a planning error for an invalid offset, not a panic. ### Notes The SQL reaches `datafusion/functions-window/src/lead_lag.rs`, where `WindowShiftKind::Lead` maps the offset through `v.neg()`. -- This is an automated message from the Apache Git Service.
