   > Thanks for the fix! I assume this change converts a core dump into a 
user-facing error. Have you looked into the cases where Spark could produce an 
out-of-range index? I'm wondering why Spark would generate this kind of plan.
   
   I tried multiple things, but I couldn't repro with simple unit test. The 
repro is at 
https://github.com/apache/gluten/actions/runs/27487184961/job/81246596702?pr=12278

 />
   
   So, I assume it is the next test:

   Suite MergeIntoNestedDataSQLPathBasedSuite
   
   The problem is this test is not a simple SQL command:

 />
