Could it be you are doing something the equivalent of:

use strict;
use warnings;

my $valuesLine = <DATA>;
my @values = split /\s+/, $valuesLine;
my %data = @values;

__DATA__
one two three four five

where instead you should initialize %data using something like:

my %data = map {$_ => 0} @values;
