Date::Manip has a memory leak that I'm trying to track down, and I guess that I simply do not understand perl internals enough to understand what is causing the leak.

A trivial test script: 
   #!/usr/bin/perl -w
   use Date::Manip::Date;
   $date = new Date::Manip::Date;
   use Devel::LeakTrace::Fast;
   $date->parse("2010-02-01 01:02:03");
shows: 
   leaked SV(0x0x1241a80) from /home/sulbeck/local/lib/perl5/5.10.1/Date/Manip/TZ/amnew_00.pm line 39
This is just one leak among many, but I figure if I can just understand one of them, I'll be able to figure out the others. There are a mixture of leaked AVs, SVs, and RVs if that matters all being reported at the same line 39.

The referenced line 39 in amnew_00.pm looks like: 
   %Dates         = (
      1    =>
        [
         [ 1,1,2,0,0,0,1,1,1,19,3,58,'-04:56:02',-4,-56,-2,
          'LMT',0,1883,11,18,16,59,59,1883,11,18,12,3,57,
          '0001010200:00:00','0001010119:03:58','1883111816:59:59','1883111812:03:57' ],
        ],
   ...
);
(there are a number of other hash elements too, but they are all of this format).

This code is used exactly once in Date::Manip::TZ: 
   no strict 'refs';
   ...
   my $mod   = $$self{'data'}{'Module'}{$zone};
   eval "require Date::Manip::TZ::${mod}";
   my %dates = %{ "Date::Manip::TZ::${mod}::Dates" };
   $$self{'data'}{'Zones'}{$zone} =
     {
      'Dates'    => { %dates },
     };
   ...
   use strict 'refs';
There are no circular references at this point (in previous versions, there were, but in the development version I'm working on now, I've removed them). I can provide the development version to anyone who wishes it.

I'll be happy to provide any additional information needed
