There's no basis in the specification, but in practice, on Linux at least,
a process that runs as pid 1 outside of a container and that exits - whether
normally or via abort() or anything else - will cause a kernel panic. So
treating that case as UB is defensible, at least until musl is ported to an
OS where pid 1 death is less dramatic.
