Let's try.
OCaml uses a garbage collector. If the values muilt by the C stub code
or manipulated by it are not registered properly, they may be either
garbage-collected accidentally, or, on the contrary, not
garbage-collected whereas they should.
The CAMLlocal, CAMLparam and CAMLreturn macros are tricks to help
programers do things correctly.
Not sure I can go much further here, sorry.
Shérab.
