Same in PHP 5.5.9-1ubuntu4. I get those occasionally too when viewing from Chrome.

Just in case it matters, I am seeing the same bug on Linux with Firefox (both Firefox releases and
Nightly builds)

I've attached a patch that disables "Unexpected EOF" error message from built-in
server.

I've noticed these messages and did some network traffic analysis.

I've tested this on Ubuntu and Chromium. What I've found is that Chromium has feature
called "Predict network actions to improve page load performance" and it's enabled by
default. It works this way, that if HTML page has links to some resources, than Chromium opens about
10 TCP connections in advance. And then if browser has less than 10 resources to fetch, unused
connections times out after 10 seconds. And this (empty payload) causes PHP server to display
"Invalid request (unexpected EOF)" message.

See: http://svn.php.net/viewvc/php/php-src/branches/PHP_5_4/sapi/cli/php_cli_server.c?revision=322966&view=markup#l1591

When you disable this Chromium's feature it doesn't open TCP connections in advance and
this error message disappears.

I'm wondering if we really need this error message (maybe it was used for some debugging
purposes).

if someone could test it, please.
