apache -X で起動すると 100% 落ちますね。なぜ multipart form を受け取っ
た場合にだけ落ちるのかまでは不明ですが、引金は Apache::request#[],
Apache::request#send_http_header のようです。cgi.rb ではこれらを使わず
に通常のヘッダ出力を行なうようにすると、落ちなくなります。

実験用のスクリプトを付けておきます。

cgi = CGI.new("html3")

cgi.out() do
  cgi.html("PRETTY"=>($DEBUG ? "  " : false)) do

      cgi.multipart_form() do
        cgi.file_field("uploaded_file") + cgi.br +
