I'm still pretty sure it's the global variable that's messing you up. Consider the odd-but-possible case where %globalHash gets new values occasionally: 
my (@array, %hash);

do_something($_) for (1 .. 3);

sub do_something {
    my $num = shift;
    $hash{$num} = $num;
    push @array, { %hash };
}

use Data::Dumper;
print Dumper(\%hash);

foreach my $href (@array) {
    my ($key, $value);
    print "Hash ($href):\n";
    foreach $key (keys %$href) {
        $value = $href->{$key};
        print "\t$key => $value\n";
    }
}

Each time through do_something(), not only does %hash get new data, but the hash reference pushed onto @array gets the old data.

This may or may not be what you want. In fact, I'm really not sure what you want. Instead of asking "How do I fix this bit of code that isn't working?" perhaps you should ask "Here is a textual description of the task I am trying to accomplish. What methods might I use to perform this task?" (XYZ Questions)
