I try to avoid Intel assembly as much as possible, so I had to think about
this. But as I suspected, this is just "int *x = &p". Since in your other
examples you include the assignment of 1337, you need to add
movl $0x539,(rax)
to this as well. As far as I can see, that makes it an additional 6 bytes,
for a total of 13.
