clone2 stack pointer passed in points to the highest address for the stack. clone3 switches this around and gives us a base pointer and a size. glibc started using clone3 for its thread cloning which finally caught this bug. Necessary to run any application under the Ubuntu 22.04 rootfs since that uses a new enough glibc to encounter this.
