Also, anybody having a couple of minutes to test and help, if you see this issue locally, could you
 - build a VM (https://github.com/pharo-project/pharo-vm/), checking out tag v10.3.2
 - run locally the failing tests

This information could help us reduce the search space, and identify if it���s just the build environment or there is something else we have to deal with.

It seems you have figured it out. Since I started to compile my own vm I cannot build anything on my jenkins.

In order to at least confirm a few things I've built a little infrastructure for me to generate vms in different combinations. I went down the rabbit hole and tried v10.21, v10.3.1 and v10.3.2 under debian 12 and all failed. Then I downgraded gcc to gcc-11 and retried. All are still failing. I read that the gcc 12 and gcc 11 more or less the same in that regard. Sadly it is not easy to go much back from where I am. I need to check on the jenkins and this is based on debian 12. So I could retry with older gccs but I'm not sure what will be the outcome. 
Right now I'm retrying with pharo-10 HEAD because your commit message sounded it is worth it (well, nothing else works)

If you want me to test somethig please just say so.
