You are wrong that OCaml string constructor allocates a copy.
OCaml Strings aren't copy-on-write so this would be expensive.

# let f () = "aaa";;
val f : unit -> string = <fun>
# (f ()).[0] <- 'A';;
- : unit = ()
# f ();;
- : string = "Aaa"

OCaml strings are technically mutable but they can't change the length.
The mutability is generally used only to construct a new string by
allocation and filling.

A typo: not 'strcmp("hello")' but perhaps strcpy or strdup (non-std).
In Ruby it's faster than strcpy under the hood because of COW.
