Bug report: Problems using cache

Hello HTML::Template developers and users,

I would like to report a bug regarding cache feature and template
objects using the same template file.

Here is the Test-Case:

* /opt/Perl/Playground/template.tmp
----------------------------------------------------------------------------
<TMPL_VAR NAME="TITLE">
<TMPL_VAR NAME="CONTENT">
----------------------------------------------------------------------------

* /opt/Perl/Playground/HtmlTmplHandler.tmpl
----------------------------------------------------------------------------
package Playground::HtmlTmplBugHandler;
use warnings;
use strict;

use Apache2::RequestRec ();
use HTML::Template ();

my $htmlTemplate = '/opt/Perl/Playground/template.tmpl';

sub handler
{
    my $rRequestRec = shift;

    my $rTmpl1 = HTML::Template->new(filename => $htmlTemplate, cache => 1);
    my $rTmpl2 = HTML::Template->new(filename => $htmlTemplate, cache => 1);

    $rTmpl1->param(TITLE => 'Title');
    $rTmpl2->param(TITLE => 'Subtitle', CONTENT => 'Content');
    $rTmpl1->param(CONTENT => $rTmpl2->output());

    # Invalid. Outputs:
    #   Subtitle
    #   Subtitle
    #   Content

=begin comment
    $rTmpl2->param(TITLE => 'Subtitle', CONTENT => 'Content');
    $rTmpl1->param(TITLE => 'Title');
    $rTmpl1->param(CONTENT => $rTmpl2->output());

    # Invalid. Outputs:
    #   Title
    #   Title
    #   Content
=cut

=begin comment
    $rTmpl2->param(TITLE => 'Subtitle', CONTENT => 'Content');
    $rTmpl1->param(TITLE => 'Title',    CONTENT => $rTmpl2->output());

    # Correct. Outputs:
    #   Title
    #   Subtitle
    #   Content
=cut

    $rRequestRec->content_type('text/plain');
    $rRequestRec->print($rTmpl1->output());
    $rRequestRec->rflush();

    return Apache2::Const::OK;
}

1;
----------------------------------------------------------------------------

* httpd.conf
----------------------------------------------------------------------------
..
<Location /html_template_bug>
    SetHandler modperl
    PerlResponseHandler Playground::HtmlTmplBugHandler
</Location>
..
----------------------------------------------------------------------------

My configuration:
        Apache/2.0.54 (Unix) mod_perl/2.0.1 Perl/v5.8.5
        HTML::Template v2.7

It seems that there is a global cache for each template file which
apparently temporary holds values as well and it doesn't really expect
that two or more instances of the same template might be used in the
same time.

Can anyone help me with this issue? Thank you in advance.

Regards,
Jozef
