I got a message "Attempt to free unreferenced scalar: SV etc" as the first line of output.

The line mentioned in the message (error message? warning message? it doesn't really say how worried I should be) is a use, and it is shown below:

use v5.8;
use strict;
use warnings;
use utf8;
use charnames ':full';

package VM_List;

my $LN= "\N{POUND SIGN}";  # used for List Name.

use overload
   '""' => \&stringify;

sub create
 {
 my ($class, $listref)= @_;
 bless $listref, $class;
 return $listref;
 }

sub stringify
 {
 my $self= shift;
 return "$LN( " . join (' ', @$self) .  ' )';
 }

return 1;  # loaded OK

Any clues what this means?

I'm running Perl 5.8.3, Activestate build 809.
