GCC14 / Ubuntu 24.10 (Beta) issues with generated code

[GWRon]

William at discord pointed out that he tried to compile stuff within a newly installed Ubuntu 24.10 (Beta). Seems they install GCC 14 by default - and this leads to the following issue in archive.mod:

Am not sure if this really is a GCC issue ... (in other words: did not try on my own in a VM ... latest Ubuntus have a lot of issues in my qemu/kvm stuff here)
