in reply to Preserving hash structure after subroutine call

May be you can follow this simple example and try modifying to see where you are getting the problem: 
use Data::Dumper;
my %myhash = {};
build_hash(\%myhash);
print Dumper(\%myhash);

sub build_hash {
    my $href = shift;
    my %results = (1,2,3,4);;
     %{$href} = %results;
#    print Dumper($href);
}

    I've used the method in your example extensively to initialise hashes and never had any problem with it. For some reason (scope?) it just doesn't seem to work when the fetchrow_hashref method is involved.
