Your function does not protect "str" from being reclaimed by the GC (which
can happen in "caml_alloc_small"), and you should use the Field-macro only
to overwrite the contents of the cons-block in this particular case, because
you had used "caml_alloc_small" as allocation function, and there was no
intermediate allocation.
