--- Comment #9 from Jan <jan at jki dot io> --- I'm using the clear linux gcc version well atleast the patches. Maybe thats the culprit. https://clearlinux.org/ But it should be easy to run that in a container. I reverted some of the patches and rebuild gcc. I will report if that solved the problem an what patch made the problems.
