That is because my hastily created example SQL was missing explicit definition
for issues.return and old_issues.return.
This wasn't the case in the code (hopefully).

Try this:

SELECT COUNT(*) as count_precedent_state,tmp.issues,tmp.onloan,tmp.return
FROM (
    SELECT it.*, i.return FROM issues i, items it
    WHERE i.borrowernumber = 1234 AND
          i.itemnumber = it.itemnumber AND
          DATE(i.issuedate) < CAST(now() AS date)
    UNION
    SELECT it.*, oi.return FROM old_issues oi, items it
    WHERE oi.borrowernumber = 1234 AND
          oi.itemnumber = it.itemnumber AND
          DATE(oi.issuedate) < CAST(now() AS date) AND
          DATE(oi.returndate) = CAST(now() AS date)
    ) tmp
GROUP BY tmp.issues,tmp.onloan,tmp.return;
