Hi, Sanja! I have no idea how this postreview fix relates to any of my review comments. Let me repeat them again: 1. Add comments 2. Add a test case with row items 3. In your test case - if you remove GROUP BY you get a crash again. This might be a different bug, though. On Aug 05, sanja@mariadb.com wrote:
