Am I doing something wrong? Here is a full script and its output. 
#!/usr/bin/perl

use strict;
use warnings;
use threads;
use threads::shared;
use Net::Pcap;

my $err;
my $dev = Net::Pcap::lookupdev(\&err);
my ($address,$netmask);
Net::Pcap::lookupnet($dev,\$address,\$netmask,\$err);
my $filter;

print "threads version -> ".$threads::VERSION." threads::shared versio
+n -> ".$threads::shared::VERSION."\n";

my $capobj:shared  = &share(Net::Pcap::open_live($dev,1024,0,0,\$err))
+;
print "shared $capobj\n";

my $capthread = threads->new(\&capture);
sleep 5;
Net::Pcap::breakloop($capobj);
print "$capobj breakloop\n";

$capthread->join();
print "Capture thread finalized\n";

sub capture {

        print "capture->$capobj\n";
        Net::Pcap::compile($capobj,\$filter,'host XX.XX.XX.XX && port 
+7777 && udp',1,$netmask);
        Net::Pcap::setfilter($capobj,$filter);
        Net::Pcap::loop($capobj,0,\&capture_callback, 0);
        print "Outside the loop\n";
        Net::Pcap::close($capobj);


}

sub capture_callback {

}

And the output: 
$perl test3.pl
threads version -> 1.67 threads::shared version -> 1.14
shared pcap_tPtr=SCALAR(0x8ee08f8)
capture->pcap_tPtr=SCALAR(0x8f223b4)
