Yeah, since this code is heavily inspired by QEMU I wanted to wait a bit to see how QEMU deals with this because allocating those few bytes looked needless to me. But I guess there's no better solution. Anyway, I've raised this issue with QEMU here: https://lists.gnu.org/archive/html/qemu-devel/2022-08/msg03128.html Michal
