No, it is not a theoretical scenario: most languages that produce native
code have the requirement to produce the final binary using their
toolchain. It is true for OCaml: you need to use ocamlopt to produce a
binary, even if using a third-party C library; I believe it is true for
The problem happens when you want to mix several of these languages,
because the requirements are incompatible.
Fortunately, most people who program in other languages than C are not
stupid enough to use them to produce libraries, except for use with that
language itself. Except c++ people, for some reason.
