Quoth the Fine Manual (8.2.1.1. Using your own main()

There can be multiple calls to |hs_init()|, but each one should be
matched by one (and only one) call to |hs_exit()|^[14

.
So this should theoretically work.
Except that [14] says: the outermost hs_exit() de-initialises, and
afterwards, cannot reliably re-initialise in current implementations.
So the currently working use-case is just:
Prog ::= nop | hs_init(); Prog; hs_exit()
