[felixgimeno]

It looks like for some reason the syscall arch_prctl is needed
can you try adding said syscall to this line and re-executing these? It should solve this error

builder.AllowSyscall(__NR_arch_prctl);

https://github.com/deepmind/code_contests/blob/fa7a4f8139aab08362503f3344778eb86901709a/execution/py_tester_sandboxer.cc#L181

I also encountered this compilation failure with Python3.9.
Adding the builder.AllowSyscall(__NR_arch_prctl); didn't work - I still got compilation issues in the example.

The only thing that solved it was to use Python 3.10 (in my case 3.10.13)
