I'm very surprised that this is even allowed. Apparently it's
Linux userspace that normally complains about it:
https://git.savannah.gnu.org/cgit/gnulib.git/tree/lib/progname.c#n54
The manpages just say
```
v - execv(), execvp(), execvpe()
The char *const argv[] argument is an array of pointers to
null-terminated strings that represent
the argument list available to the new program. The first
argument, by convention, should point to
the filename associated with the file being executed. The
array of pointers must be terminated by
a null pointer.
```
With nothing to the contrary, I'd take "must be terminated by a
null pointer" as "can't itself be a null pointer".
On OpenBSD this fails outright:
```
RET execve -1 errno 14 Bad address
```
You can get `execv` from `core.sys.posix.unistd`
