Subject: Search for the smallest possible possible Ocaml segfault....
Date: Thu, 8 Nov 2007 09:17:09 -0500	[thread overview]
Message-ID: <9d3ec8300711080617g1b023711o1a8f9aa50b7874@mail.gmail.com> (raw)

I have a  open bug in ocaml
(http://caml.inria.fr/mantis/view.php?id=4321) that leads very simply
to a segfault. The bug has been there for more than 4 months and is
still marked as "new". Since it seems to be stalling I thought I might
give it a gentle prod: what is the smallest possible ocaml program you
can come up with that leads to a reproducible segfault without using
FFI's Obj or Marshal. Here is mine:

Scanf.sscanf  "\"%2$c%1$s\"" "%{%c%s%}" (fun f->Printf.printf f 'x' "xy");;

My point of view would be to disable positional parameters until they are fixed.
Till
P.S.: I am very grateful for the great work the INRIA's team, my
intention is not to criticise it. My impression was that bug reported
via the mail ling list were acknowledged faster, I'm putting this
theory to the test.
