This is a known bug in OCaml 3.00.  A simple fix is described here:

    http://caml.inria.fr/bin/caml-bugs/fixed?id=94

and of course this will be fixed in OCaml 3.01.

Concerning bounds checks for bigarray accesses: you are correct that
the current implementation always perform them, there is no equivalent
to Array.unsafe_{get,set}, and the -unsafe flag simply doesn't apply
to bigarrays.

The party line on unsafe array accesses is unclear: on the one hand,
we do not want to encourage their use, as it can break type safety and
dramatically reduce the safety of the programs; on the other hand,
they are handy when benchmarking against C or Fortran :-)

I'll keep that in mind for 3.02.
