That warning comes from the error handler. 

sub _error {
    my $sock = shift;
    my $err = shift;
    {
      local($!);
      my $title = ref($sock).": ";
      $@ = join("", $_[0] =~ /^$title/ ? "" : $title, @_);      <-- 83
      close($sock)
    if(defined fileno($sock));
    }
    $! = $err;
    return undef;
}

It's not $title that's undef because that would cause the match operator to warn too. It's one of the arguments.

The warning is inconsequential. It's just the symptom of another bug, a bug that's already being reported as an error by Socket. _error is only called from the constructor, so that means the constructor is failing. What error is being returned when you try to create the socket?
