caml_alloc() takes units of Wsize (word size), not bytes. As a consequence, we're allocating 4 or 8 times too much memory. Ocaml has a helper, Wsize_bsize(), but it truncates cases which aren't an exact multiple. Use a BUILD_BUG_ON() to cover the potential for truncation, as there's no rounding-up form of the helper. Fixes:8b7ce06a2d("ocaml: Add XC bindings.") Fixes:d3e649277a("ocaml: add mmap bindings implementation.")
