Debugging threaded code

[Gangabass]

I'm using Komodo IDE but get this error while using Komodo's debugger: <cite>Thread 1 terminated abnormally: Undefined subroutine &Dos::CLONE called at C:\Users\roman.2GIS\Dropbox\Projects\Uncompleted\gkhambat\Basketball parser\scraper.pl line 23.</cite> And this is line 23 (i have no any Dos subroutine anywhere):

#!/usr/bin/perl

use strict;
use WWW::Mechanize;
use FindBin qw($Bin);
use Thread::Queue;
use HTML::TreeBuilder::XPath;
my @threads =
  map { threads->create( \&create_thread, $_ ) }
  ( 1 .. $config->{NUMBER_OF_THREADS} );

So all threads are terminated immediately after start. In the previous versions of Komodo i have no such issue. What i can do with this? Thanks. Roman
