vijesh has asked for the wisdom of the Perl Monks concerning the following question:

hi experts, I use v5.8.8 built for i386-freebsd-64int for perl and perl5db.pl version 1.28 for perl debugger. I am trying to push values of hash %pdi like following. Script bumped out with "Bizarre copy of HASH in leave" only when working with perl debugger. 

@{%{$pp->{FEATURES}{$rtag}}}{keys %$pdi} = (values %$pdi);

  DB<4> x %$pdi
0  'CONFIG'
1  HASH(0x1126a154)
   'SET' => ARRAY(0x10ef7f64)
      0  'command 0'
      1  'command 1'
2  'ROLE'
3  HASH(0x10ef7598)
   'pe' => ''
  DB<5>

    that code is broken , it uses symbolic references

    you probably meant 

    #!/usr/bin/perl --
use strict; use warnings;
my $rtag = 'WHAT';
my $pp = { FEATURES => { WHAT => {} } };
my $pdi = { 1,1,2,2,3,3 };
@{
    $pp->{'FEATURES'}{$rtag}
}
{
    keys(%$pdi)
} = values(%$pdi);
use Data::Dump;
dd $pp;
dd $pdi;
__END__
{ FEATURES => { WHAT => { 1 => 1, 2 => 2, 3 => 3 } } }
{ 1 => 1, 2 => 2, 3 => 3 }
