@Yohahaha Thank you. I will take a look later.

This is caused by the last operator C2R, and toArray uses the memory freed by the iterator. @JkSelf has a fix maybe can resolve the problem.

@Yohahaha This is a bug for spark 3.2 and 3.3. And we have merged PR#40914 into spark 3.3 to fix this issue. I will port this fix in Gluten later. Thanks.

Good to know this!
