But something is indeed broken.  Here's a slight variant of the above:

        Objective Caml version 3.07+2

# let e = Failure "test";;
val e : exn = Failure "test"
# let e' = Failure "test";;
val e' : exn = Failure "test"
# let e'' =  Marshal.from_string (Marshal.to_string e []) 0;;
val e'' : 'a = <poly>
# e'' ^ "good-bye";;
