Hi,


I have a Windows machine and I have Cygwin installed. I have a Perl script
which calls a shell script using Cygwin. I am getting the following message
while running the Perl script:
---------------------------------------------------------------------------=

I searched various links, and tried out different suggestions that worked
for others but to no avail. Few things that I tried was:
--------------------------------------------------
1.	Disabled SEP (Symantec Endpoint Protection)
2.	Turned off DEP (Data Execution Prevention) for Cygwin=E2=80=99s sh.exe
3.	Modified numbers (xxxx,yyyy,zzzz) present in Windows key value at the
following path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session
Manager\SubSystems\
4.	Ran rebaseall in ash.exe
--------------------------------------------------

The strange thing is that if I directly call the shell script using Cygwin,
it works fine.
c:\cygwin\bin\sh.exe c:\myscript.sh

cygcheck  -V gave the following output:
--------------------------------------------------
$ cygcheck  -V
cygcheck version 1.123
System Checker for Cygwin
Copyright (C) 1998 - 2008 Red Hat, Inc.
Compiled on Apr 12 2010
--------------------------------------------------

I think this version of Cygwin is quite old so I am planning to install a
separate instance (latest) but what concerns me is that since the shell
script works fine without using Perl, and fails when using Perl, there seems
to be some issue either with
----------------------------------
1. Perl itself
2. compatibility between Perl & Cygwin versions
----------------------------------

I have also attached the output of =E2=80=98cygcheck -s -v =E2=80=93r=E2=80=
=99. However, I have
modified/removed few sensitive info.

Can anyone provide some help to get this thing working?


Thanks,
Gaurav
