Hello, ... I just uploaded ocaml 3.02-3, which should fix the alpha floating point exception bug. As there is no alpha box available, i cannot build it by myself and test it, so please someone with an alpha box out there, could you build the alpha version and upload it, and then check the following : % ocaml Objective Caml version 3.02 # 1.0 +. sqrt(-1.0);; And tell me the result of this ... Friendly, Sven Luther
