you are right. I make a simpler program just to reproduce the problem.
See the code belowe ( File Test1.pm )
#!/usr/bin/perl -w # package Test1; use strict; use warnings; use utf8; use CGI; use HTTP::Lite; use HTTP::Request; use LWP::UserAgent; use XML::Simple; use XML::DOM; use Tie::File::AsHash; use IO::Socket; use Sys::Hostname; use IPC::Shareable; use Data::Dumper; my ( $fileTie ) = '/var/log/www/benzopmvutil.dat'; my ( $log_filename ) = '/var/log/www/test1.dat'; my %conf_data = ( 'test1' => 'abc' , 'test2' => '123'); my $test = Test1->new( \%conf_data ); # ================================================ # ================================================ sub new { my $that = shift; my $params = shift; my $class = ref($that) || $that; my $self = {}; bless($self, $class); tie %$self, 'Tie::File::AsHash', $fileTie, split => '=' or die "P +roblem tying %$self: $!"; $self->{counter} += 1; if( $self->{counter} > 9999 ) { $self->{counter} = 1; } $self->{last_call} = scalar localtime; my $s1 = Dumper( $self ); my %ipcshare_options = ( key => 'benz', create => 1, exclusive => 0, mode => 0666, destroy => 0, size => IPC::Shareable::SHM_BUFSIZ() ); my %shared_data = ( 'dtLastRcvMsg' => time, 'dummy2' => 33, 'dummy' => 5 ); my ( $p1, $p2 ); # 1° test : OK $p1 = \%shared_data; $self->mylog( "P1: ($p1) " .

=======================================
The output is the one below

As you can see , it seem that when I assign the hash reference to an element of another hash I then I read it back, it's value it's corrupted.
BTW : my revision of perl is the 5.6.1 and I run it on red-hat 7.3 and slackware 8 Belowe the full status of my perl installation, my be it should be usefull
