Dear Brotheren and Sisteren,

I'm getting an error I just don't uderstand using the following code:

#!/usr/bin/perl -w
use strict;
use Net::FTP;
my $ftp = Net::FTP->new('ftp')
    or die("unable to connect: $@\n");
$ftp->login or die("Unable to login to ny4");
print "Message = ", $ftp->message(), "\n";
$ftp->put( 'foo' )
    or die("Unable to write ftp.prep");
print "Message = ", $ftp->message(), "\n";
$ftp->quit;

The error is:

Use of uninitialized value in -f at /opt/perl/lib/site_perl/5.6.1/Net/
+FTP.pm line 716.
[download]

The error points to this section of code in Net::FTP

sub _store_cmd 
{
 my($ftp,$cmd,$local,$remote) = @_;
 my($loc,$sock,$len,$buf);
 local *FD;

 my $localfd = ref($local) || ref(\$local) eq "GLOB";

 unless(defined $remote)
  {
   croak 'Must specify remote filename with stream input'
    if $localfd;

   require File::Basename;
   $remote = File::Basename::basename($local);
  }
 if( defined ${*$ftp}{'net_ftp_allo'} ) 
  {
   delete ${*$ftp}{'net_ftp_allo'};
  } else 
  {
   # if the user hasn't already invoked the alloc method since the las
+t 
   # _store_cmd call, figure out if the local file is a regular file(n
+ot
   # a pipe, or device) and if so get the file size from stat, and sen
+d
   # an ALLO command before sending the STOR, STOU, or APPE command.
   $ftp->_ALLO(-s _) if -f $loc; # no ALLO if sending data from a pipe
  }

The line:

$ftp->_ALLO(-s _) if -f $loc; # no ALLO if sending data from a pipe
[download]

is line 716, as mentioned in the error message. From what I can tell $loc is not set in the preceding code.
Does anyone have any ideas?

The file is transfered succesfully, no problem connecting or logging in. The only trouble is the error message.
