Unfortunately, we are still doing this in quite a lot of places in the QEMU code and some of them are not easy to fix. So for the time being, temporarily switch this off in the failing clang-system job until all spots in the QEMU sources have been tackled. Signed-off-by: Thomas Huth Reviewed-by: Daniel P.
