Summary

0004411: ocamlrun crashes calling Unix.access on Windows

Description

Microsoft Windows XP [Versione 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.

c:\>ocaml
Objective Caml version 3.10.0

# #load "unix.cma";;
# Unix.access "" [Unix.X_OK];;

At this point Windows displays a message that the application died.
With other access_permission parameters it works.
Probably for the same reason, I can't open the shell with OCamlBrowser.

Notes
(0004175) xleroy (administrator) 2007-10-09 16:35	The Windows/CRT version of access() does not implement the X_OK check. Old versions of the CRT would either return an error or ignore the X_OK bit. Newer versions do so-called "parameter validation" which, by default, does a "Watson" crash reporting. Sort-of fixed in 3.10 development branch by treating X_OK as R_OK, i.e. just test that file is readable. It looks like the best effort we can do at this moment. Will document it in manual. Fix needs testing.
