Fizzbuzz by hand-crafting AMD64 instructions at runtime in OCaml (github.com)

This allocates required number of pages using mmap, fills it with AMD64 instructions, changes the memory protections and execute the memory as code.

This works fine on my machine, but I'm not sure if it's guaranteed to work in all cases. I assume it's safe to execute arbitrary asm code from OCaml. I'm not sure if the conversions I do are valid.
