</div>Hi Hiro,<br>
<br>
do you have a test case that let's us reproduce this bug on one of the normal plugins? This would help in tracking down the problem.<br>
<br>
I was under the impression that Jonathan's patch<br>
<br>
<a href="https://github.com/LITMUS-RT/litmus-rt/commit/4ffefb822b9d65d4efbedb60e3c9a0e76895cc5b" target="_blank">https://github.com/LITMUS-RT/litmus-rt/commit/4ffefb822b9d65d4efbedb60e3c9a0e76895cc5b</a><br>
<br>
solve this problem already. Maybe we have not completely solved the problem yet? Or did I reintroduce it with the latest patch?<br>
<br>
<a href="https://github.com/LITMUS-RT/litmus-rt/commit/39d902832855cbd2baf45ac8943879be3ad8ca5a" target="_blank">https://github.com/LITMUS-RT/litmus-rt/commit/39d902832855cbd2baf45ac8943879be3ad8ca5a</a><br>
<br>
Could you please try if the problem still occurs if patch 39d902832855cbd2baf45ac8943879be3ad8ca5a is missing?<br>
<br>
Thanks,<br>
