Subject: [Caml-list] Compiler killer code?
Date: Sat, 08 Jun 2002 16:32:13 +0200 [thread overview]
Message-ID: <3D02156D.7070303@baretta.com> (raw)
Is the type inference algorithm guaranteed to termintate? I
ask because I have accidentally attempted to evaluate a
(meaningless) function which almost hanged my Athlon.
The killer code is the following:
type t = t -> t
let f (x:t) :t = f f
If I type this into the toplevel, it starts to allocate
memory by the tens of megabytes, until I have to kill it to
prevent a system crash. I let it reach approximately 128MB
before killing it. (BTW, that was with ocaml 3.04+13
2002-06-05.)
Is the language really supposed to accept such garbage as
that which I wrote?
Alex
