I've got a commandline script, and I wanted to do some stuff before ending the program if somebody hit Ctrl^C.

I'm using ActivePerl and I've tried: 

#!/usr/bin/perl -w
use strict;

$SIG{INT}=\&myhand;

sub myhand
{
    print "\n caught $SIG{INT}",@_,"\n";
}

print "program started \n";
while(1){sleep 1;}

I need to hit Ctrl^c twice to kill the program.
If I add exit; or die; at the end of myhand, perl crashes (PERL caused an exception c0000026H in module KERNEL32.DLL at 015f:bff88510.).

How do I fix this?
I've read perlman:lib:sigtrap and I've also tried: 

use sigtrap 'handler' => \&myhand, 'INT';

sub myhand
{
    print "\n caught $SIG{INT}",@_,"\n";
}

print "program started \n";
while(1){sleep 1;}

which should be the same as my first example, but it also doesn't work (same errors as before).
