Artisan服务发送带有嵌入响应头的资产

Maybe this is something obvious but I'm having a hard time, I just found out that my local PHP environment is delivering static files with the response headers embedded.

This is Laravel 4.1.26 with PHP 5.5.11 on Fedora 20, already tested laravel serve and php -S localhost:8000 server.php, both with equal results.

I tried with Firefox, Opera and Chromium, it looks like is displaying the raw binary response:

This is causing errors on all my js files.

For what is worth I tried curl and wget -q -O - and the responses are ok, no headers displayed. This looks like PHP's built-in server issue, where should I dig first?

EDIT:

This is not a PHP thing, it has something to do with Laravel's emulation of mod_rewrite with the file "server.php", if I step on the public folder and launch the server with php -S (ignoring server.php and laravel serve) then is all fine.

EDIT2:

Just narrowed the search, artisan serve runs ok in Debian 8 Jessie with the same PHP version (5.5.11), something is different in the Fedora environment.

just change:

if ($uri !== '/' && file_exists(__DIR__.'/public'.$uri)) {
   return false;
}

to

if ($uri !== '/' && file_exists(__DIR__.'/public'.$uri)) {
ob_end_clean ();
   return false;
}

it solved it for me
