Hi Monks,

I wanted to share an array between to processes created by fork(), but the following code is broken and I have no clue why:

use strict;
use diagnostics;
use IPC::Shareable;
use POSIX ":sys_wait_h";

my @data;
my %options = (
    create    => 1,
    exclusive => 0,
    mode      => 0644,
    destroy   => 1,
);
my $pid;
my $item;

   if ( ! defined ( $pid = fork() ) ) {
   
      die( "Cannot fork!: $!" )

   }
   elsif ( $pid == 0 ) {
      
      # Child
      #tie( @data, 'IPC::Shareable', 'glue', \%options );
      sleep 1;

      for ( my $i=1; $i <= 10; $i++ ) {
         
         $item = shift( @data );
         if ( ! defined $item ) { $item = '' }
            
         print "Child: $item\n";
         
      }
      
   }
   else {
      
      # Parent
      tie( @data, 'IPC::Shareable', 'glue', \%options );
      
      for ( my $i=1; $i <= 10; $i++ ) {
         
         push( @data, $i );
         print "Parent: @data\n";
         
      }

      waitpid( $pid, WNOHANG );
}

It yields: 
Not an ARRAY reference at /usr/local/share/perl/5.20.2/IPC/Shareable.p

        362 (#1)
    (F) Perl was trying to evaluate a reference to an array value, but

    a reference to something else instead.  You can use the ref() func

    to find out what kind of ref it really was.  See perlref.

Any idea?
