alamb opened a new issue #1676: URL: https://github.com/apache/arrow-datafusion/issues/1676
**Describe the bug** If we try to merge two streams that are non overlapping (e.g. `0..20` and `20..40`) then the following panic is produced: ``` thread 'test_merge_2_no_overlap' panicked at 'assertion failed: i < self.len()', /Users/alamb/.cargo/registry/src/github.com-1ecc6299db9ec823/arrow-8.0.0/src/array/array_primitive.rs:120:9 note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace ``` Note this won't affect any users of DataFusion unless they are using externalized sort that @yjshen has recently been working on. **To Reproduce** I have a fuzz tester I will contribute and link to this issue. **Expected behavior** Correct answers come out, with no panic **Additional context** Found in some of our tests in IOx: https://github.com/influxdata/influxdb_iox/issues/3530 I am fairly confident it is a corner case in the code from https://github.com/apache/arrow-datafusion/pull/1596 -- This is an automated message from the Apache Git Service.
