Description Tim Speetjens 2014-10-08 12:13:03 UTC 
Description of problem:
When a child process is started, and finished before a call to wait, an error is signaled.

Version-Release number of selected component (if applicable):
zsh-4.3.10-7.el6.x86_64


How reproducible:
100%

Steps to Reproduce:
Run the following script with zsh (or with zsh in ksh emulation mode):
#!/bin/ksh
sh -c "echo done" &
pid1=$!
sleep 1
wait $pid1
echo "rc: $?"

sh -c "exit 3" &
pid2=$!
sleep 1
wait $pid2
echo "rc: $?"

Actual results:
$ zsh test.sh
done
test.sh:wait:5: pid 6156 is not a child of this shell
rc: 1
test.sh:wait:11: pid 6159 is not a child of this shell
rc: 1


Expected results:
$ zsh test.sh 
done
rc: 0
rc: 3


Additional info:
This is equally so for running zsh in ksh emulation mode. Running the same script with either bash or mksh, produces the expected result.

We already had a RHEL-7 sibling of this bug, merging...
