This looks like a false positive to me, which might be the result of some missed optimization in the compiler when building with certain options. I see in the .config that KASAN is enabled, and this sometimes causes odd behavior like this. If it does not happen without KASAN, maybe report it as a bug against the compiler. Arnd
