Here's a patch to allow ocamldebug to display the value of float array
variables in the debuggee---currently it terminates with an
uncaught [Debugcom.Marshalling_error].

Sorry, wasn't functioning late at night and got inelegant error
handling (though functionally correct). Here's the right thing in case
anyone wants to use it as the base of a fix in the CVS.
