[cups] "FAIL: 62 job control files were not purged" when building CUPS 2.2.3

[Alex Korobkin]

I can't seem to build CUPS 2.2.3 on Ubuntu, it stops at "FAIL: 62 job
control files were not purged" error during run-stp-tests.sh run.

However, editing the line 2743 in scheduled/job.c from
else if (!JobHistory && !job->printer)

back to (as was changed from 2.2.2 to 2.2.3)

else if (!job->printer)

seems to fix the issue.
Is it a bug or am I missing something?
