Suggest checking that PRs assert that insertions into sets or maps expected to be adding new values didn't actually just replace some existing value.
Bug #7048 and its several duplicates would have been caught sooner if the insertion of the new spill temporary into the
spilled_composites
table had asserted that there was no existing spill variable for that expression.I don't have strong feelings about this, just a thought.
