I guess the problematic wait command output is job exit status report. To
confirm my guess, could your share example of the wait command output?
Based on my guess, I checked difference between bash 4.4 and my bash 5.1, but I
did not find notable bash code change about job exit status report. Hmm.
Your patch covers several waits in the block group. I suspect other waits in
other groups may have same risk. Instead of your patch, could you try the patch
below on your system? If it works, all waits in all groups can be addressed.
