Did anybody else see such problems? I've definitely seen the same issue as Cornelia in my Gitlab CI builds for the ESP security fixes (first version of which appeared just before rc0). The user builds always fail on "run-tcg-tests-s390x-linux-user" for me. Looking back through my gitlab CI history for the ESP patches I first see the issue in clang-user here: https://gitlab.com/mcayland/qemu/-/pipelines/278781899 (master: ec2e6e01) and for the PR I just sent the failure is now present in build-user: https://gitlab.com/mcayland/qemu/-/pipelines/285320238 The last build I have that succeeded before seeing the clang-user failure is this one: https://gitlab.com/mcayland/qemu/-/pipelines/271328298 (master: 757acb9a) That seems to suggest that the issue was first introduced in git master somewhere between 757acb9a and ec2e6e01.
