See some test failures, related to gdb:
https://github.com/p-b-o/qemu-ci/actions/runs/40776744817/job/123131480244
Ah hmm I had similar failures due to too old gdb, I might have
missed to check the version in that container image. IIRC
Gustavo had similar problem with ARM I'll see how he fixed
that (I suppose check gdb version and skip the tests).
Thanks!
