Thank you, Denis. I use a pretty stupid (but simple) workaround: I setup and compile deal.ii myself since all dependencies are compiled and use the cmake command used by spack. That works. And I do not get the serialization error.
However, now my code runs on the machine I installed it on. But once I use slurm to distribute the job across nodes I get "illegal instruction" erros. Frustrating. Nevertheless, thanks for your hint.
