hi,

well this is probably the obvious one but i'm stuck and i don't now how to get out from it. i have a subroutine (obj. method) in a class that creates two hashes which i want to pass into my main script(program). 


package Tool;
use strict;


sub new {
# construct...
}

sub _init{

# initialise...
}

sub create {

my $self = @_;

bla bla... create %hash1 , %hash2 ...

my @vi = qw(\%hash1 \%hash2);

return @vi;
}


##############

main program

#################

use strict;
use lib "./temp"
use Tool;

...

my $tree = Tool->new();

my @array = $tree->create();

#i did the separation of variables on purpose ...
 
my $first = $array[0];
my $second = $array[1];
my %hashfirst = %$first;
my %hashsecond = %$second;

########

and now it dumps %hashfirst on <b>" print Dumper(%hashfirst)"</b>;
but it doesn't want to dump the second one (%hashsecond)...

also if i pass the hashes directly it uses 3x the memory , but in this way only 80MB RAM. so my question is why does this happen?
