This is a temporary table (with no indexes) that gets created in the =
same
transaction block as the SELECT gets run, but I tried creating an index =
on
the ean column anyway with no luck:

CREATE INDEX ean_idx ON TMPTABLE USING btree (ean);
SELECT  DISTINCT ON (ean)
	ean,
	count(*)
FROM    TMPTABLE
WHERE   code NOT IN (SELECT code FROM stock_deleted)
 AND    ean IS NOT NULL
GROUP BY ean;

Still returns:
 	3246576919422	2

Wild guess - have you tried reindexing this table? I haven't seen
corrupted indexes since 7.1, though - it usually means subtle hardware
problems.
