SQLC panics when generating query for aggregating the result of a UNION

[eattoe-ctoken]

Version

1.29.0

What happened?

sqlc generate will panic when trying to generate the following sql query:

-- name: AllThingsTrue :one
WITH t AS (
    SELECT thing, bool_thing FROM things
    WHERE things.thing = $1
), ot AS (
    SELECT thing, bool_thing FROM other_things
    WHERE other_things.thing = $1
)
SELECT 
    thing, -- This column is TEXT
    bool_and(bool_thing)
FROM (
  SELECT thing, bool_thing FROM t
  UNION
  SELECT thing, bool_thing FROM ot
)
GROUP BY thing;

Relevant log output

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x2 addr=0x0 pc=0x105448320]
