Good day bretheren. I am trying to use mod CGI with POST input and am getting a stange error. Here is the (simplified) code:
#!/usr/bin/perl -w
use strict;
use HTTP::Daemon;
use CGI qw/:standard/;
my $d = HTTP::Daemon->new(LocalPort => 8080) || die;
while (my $c = $d->accept) {
    while (my $r = $c->get_request) {
        my $uri = $r->uri;
        $ENV{REQUEST_METHOD} = $r->method;
        $ENV{CONTENT_TYPE}   = join('; ', $r->content_type) || '';
        $ENV{CONTENT_LENGTH} = $r->content_length  || '';
        $ENV{SCRIPT_NAME}    = $uri->path  || 1;
        $ENV{QUERY_STRING}   = $uri->query || '';   
        my $q = new CGI;
        my $reply;
        my $scriptname = $ENV{'SCRIPT_NAME'};
        #$q =  new CGI;
        if ($scriptname =~ /start/) {
            $reply = $q->header;
            open(IN,"test.htm") or die "Can't open input: $!\n";
            while(<IN>) {
                $reply .= $_;
            }
            close IN;
        }
        elsif ($scriptname eq '/process') {
            my @params = $q->param;
            $reply = $q->header;
            $reply .= $q->start_html.$q->h2("Parameters").join('<br>',
+@params).$q->end_html;          
        }
        $c->send_response($reply);
    }
    $c->close;
    undef($c);
}

and here is the test.htm it uses 
<html>
<body>
<form method="post" action="process" enctype="multipart/form-data">
<input type="checkbox" name="cb" value="on" /><input type="text" name=
+"label" value="foobar" size="40" />
<input type="submit" name=".submit" />
</form>
</body>
</html>

I get the initial page with localhost:8080/start. Upon clicking SUBMIT I get error Use of uninitialized value in pattern match (m//) at (eval 22)[C:/Perl/site/lib/CGI.pm:829] line 4.. If I step through the code with the (Komodo) debugger, it goes into an infinite wait at my $q = new CGI;. I found that if I delete the enctype argument from the form tag in the htm file, I get no error and the infinite wait, debugger or no.

I found this thread that seems to discuss a similar problem, but it's talking about file uploads and anyway is four years old so I would think that this particular bug has been worked out by now.

Anyone know what the problem is here?

Thx...Steve

Edit: g0n - corrected link format

Update: In the code above I commented out the second CGI constructor, a mistake caught by Chromatic. But that didn't fix the problem. Also based on his opinion that CGI didn't have the proper filehandle, and the old thread linked above, I tried inserting local *main::STDIN = $c; right before the CGI constructor, and that didn't fix things either.
