At one place, we loop through the `es_result_relations` array and a size mismatch there will cause problems. Interestingly, in v14 and above, we read from `es_opened_result_relations`, which is a List, so it should be safe. I will try some tests on v13 to see if they result in crashes. But it seems quite likely by reading the code. Thanks, Pavan
