## Message

```
Write page zero as first segment for Mach-O exes

According to the Mach-O file format reference, the first
load command should be a `__PAGEZERO` segment command. The
segment is located at virtual memory location 0, has no protection
rights, and causes acccesses to NULL to immediately crash.
