Yeah, I gave the "volatile" approach a try, but reusability is almost
nil. Sooner or later I'll have to copy a payload somewhere for testing
(easiest example: in a stack array), so I am back to my original issue:
generate trivial MD code in pure-C, and have a way to copy it
arbitrarily at any place in memory.
