Sorry, I forgot to CC the mailing list in my previous reply. Re-sending this to the list for the record.
We later tried writing minimal reproducible code, but we couldn't reproduce the problem. I'm wondering if this is an extreme edge case? Did you change the job control system and the external command exit code capture mechanism in versions 4.4.23 to 5.0.0? If these improvements prevented the problem from recurring, then we decided to give up on further troubleshooting. Do you think our approach is reasonable?
