    Tried as you suggested, and there was no change at all :/

    C:\>test.pl 1

      Could you post the output from perl -V on the affected system?

        I included that in my first reply to you, but I will add it in to my original post for clarity. Both 2012 systems are using active state perl 5.18.2 
        C:\>perl -v

This is perl 5, version 18, subversion 2 (v5.18.2) built for MSWin32-x
+64-multi-thread
(with 1 registered patch, see perl -V for more detail)
