Show loop binding position in EXPLAIN VERBOSE. Use this mode in debug trace, but not in existing test .expected.
Add a YAML version of one of the incidents that shows the failure.
Freeze a ProjectedRow that exits the inside of a (non-pipelined) Map_NestedLoops, the same way it is frozen by Sort_InsertionLimited.
Make the SUM YAML test have a scale other than 0. Try to avoid trailing zeros so test runs in Python, too.
Make SUM(DECIMAL) picking to get the right scale / precision.
