Description of problem:

%hash = %{$ini{$section}} stopped working after 2.72 upgrade.

Version-Release number of selected component (if applicable):

2.72-1.el5

How reproducible:

Always (see test case below).

Steps to Reproduce:

manpage quote:
==============

%hash = %{$ini{$section}}

Using the tie interface, you can copy whole sections of the ini file into another hash. Note that this makes a copy of the entire section. The new hash in no longer tied to the ini file, In particular, this means -default and -nocase settings will not apply to %hash.

test.ini file:
==============

[section1]
  key = val11
  coo = val12
[section2]
  fookey = foo
  barkey = bar
  bazkey = baz
[section3]
  kiki = val31
  cookie = val32

test.pl file:
==============
#!/usr/bin/perl -w

use strict;
use Config::IniFiles;
use Data::Dumper;
$Data::Dumper::Indent = 3;

my %hash;
my $key;

tie %hash, 'Config::IniFiles', ( -file => "test.ini" ) ;
print Dumper(\%hash);
for $key ( keys( %hash ) ) {
    print "+$key\n";
}
print "The source is " . $hash{'section2'}{'barkey'};
print "\n========================================\n";
my %copy = %{$hash{'section2'}};
print "The copy is " . $copy{'barkey'};
print "\n";

  
Actual results:

$ ./test.pl
$VAR1 = {
          'section1' => {},
          'section2' => {},
          'section3' => {}
        };
+section1
+section2
+section3
The source is bar
========================================
Use of uninitialized value in concatenation (.) or string at ./test.pl line 20.
The copy is

Expected results:

Last line should read "The copy is bar" (error message shouldn't be there either).
