Greg Bowyer commented on ARROW-10943:
-------------------------------------
I managed to nail down a deterministic test, looks to be RLE encoding related.
{code:java}
#[test]
fn test_bool_bug() { const total: usize = TEST_SET_SIZE;
const type_length: i32 = -1; let mut encoder =
create_test_encoder::<BoolType>(type_length, Encoding::RLE);
let mut decoder = create_test_decoder::<BoolType>(type_length,
Encoding::RLE); //let mut values = <T as
RandGen<T>>::gen_vec(type_length, total); let values: Vec<bool> = vec![
