The test is a "waitFor" which implies it might be timing out or otherwise timing sensitive.. Maybe try repeatedly with each flag? Interestingly enough, I got same test failure right now, but in another place of the test. It happened when in the same time CPU was compiling 4 packages ( two of them are librewolf and firefox ) in parallel.

I've repeated emerging the package again under the high CPU load, now test time for the test was not 5.48s , but 10.66s, and it failed in the same way.
Then I wrote a simple script to check how many times it fails and with what return code.
Here's the bash script:
```
#!/bin/bash
POSITIONAL_ARGS=()
while [[ $# -gt 0 ]]; do
case $1 in
-c | --counter)
HOW_MANY_TIMES_TO_TRY_THE_PROGRAM="$2"
shift # past argument
shift # past value
;;
-e | --execute)
EXECUTABLE_PATH="$2"
shift # past argument
shift # past value
;;
--default)
DEFAULT=YES
shift # past argument
;;
-* | --*)
echo "Unknown option $1"
exit 1
;;
*)
POSITIONAL_ARGS+=("$1") # save positional arg
shift # past argument
;;
esac
done
set -- "${POSITIONAL_ARGS[@]}" # restore positional parameters
echo "HOW_MANY_TIMES_TO_TRY_THE_PROGRAM = ${HOW_MANY_TIMES_TO_TRY_THE_PROGRAM}"
echo "EXECUTABLE_PATH = ${EXECUTABLE_PATH}"
echo "DEFAULT = ${DEFAULT}"
if [[ -n $1 ]]; then
echo "Last line of file specified as non-opt/last argument:"
tail -1 "$1"
fi
for time in $(seq 0 "${HOW_MANY_TIMES_TO_TRY_THE_PROGRAM}"); do
${EXECUTABLE_PATH}
((histogram[$?]++))
done
echo "================================================================================="
echo "================================================================================="
echo "================================================================================="
echo "Simple histogram of return codes: ( format: code how_many_times)"
for length in "${!histogram[@]}"; do
printf "%-1s %s\n" "${length}" "${histogram[$length]}"
done
```
The script is called in next way:
```
bash ./test.sh -c 100 -e /var/tmp/portage/kde-apps/dolphin-23.08.5-r1/work/dolphin-23.08.5_build/bin/kitemlistcontrollerexpandtest
```
When no CPU load:
```
Simple histogram of return codes: ( format: code how_many_times)
0 101
```
When under `strees-ng -c $(nproc) --cpu-load 100`:
```
Simple histogram of return codes: ( format: code how_many_times)
0 78
1 23
```
When under `strees-ng -c $(nproc) --cpu-load 100` and `stress-ng --fork 100` :
```
Simple histogram of return codes: ( format: code how_many_times)
0 3
1 98
```
So, I guess Sam's theory seems to be true
Please test with 24.05.2, now that it is stable. (In reply to Andreas Sturmlechner from comment #14) > Please test with 24.05.2, now that it is stable.
