in thread Argument isn't numeric in numeric ge

I added the [] chars around $version_on_disk and $version_dns to make sure no strange characters were coming on the variables. They print correctly on the terminal.
How can you detect a sound in brackets? Use Data::Dumper (plus $Data::Dumper::Useqq=1; as advised by jethro) or pipe your output to a hexdump.

    ok: 
    use Data::Dumper;
print Dumper $version_on_disk, "disk";
print Dumper $version_dns, "dns";

    gives 
    $VAR1 = '1195874';
$VAR2 = 'disk';
$VAR1 = '1195874';
$VAR2 = 'dns';

    Update: with $Data::Dumper::Useqq = 1 ; I see an extra char indeed: 
    
$VAR1 = 1195874;
$VAR2 = "disk";
$VAR1 = "\a1195874";
$VAR2 = "dns";

    So now I have to figure out why it gets here and how to get rid of it. Thanks! (no votes left today, I'll appoint votes tomorrow)
