~~~
Unfortunately:
1) I don' have better reproducer then to run the whole test suite and even then it is not triggered always. I was not successful to hit the issue running just the single test case or the test file.
2) I have failed to reproduce this on CentOS Stream 9, which is surprising.
Luckily, I can reproduce it on my system.
This is seems to be related to LTO, because I have never faced such issue with LTO disabled.
