Subject: [Caml-list] A grave bug in logical shift right op?
I'm using the debian package in testing....

orion:fealn-attack$ ledit ocaml
        Objective Caml version 3.07+2

# Printf.printf "%X" 0xffffffff;;
7FFFFFFF- : unit = ()
# Printf.printf "%lx" (Int32.of_int 0xffffffff);;
ffffffff- : unit = ()
# -1 lsr 24;;
- : int = 127
# Int32.shift_right_logical (Int32.of_int (-1)) 24;;
- : int32 = 255l

What's going on here? Something's eating the most significant bit in
both hexadecimal output routine and the logical shift right
operator. Somebody please help me! My cipher isn't working!!!

Confused,
