And more update:
I also have similar setup on the server where problem occurs:
Apache version 2.2.25
PHP version 5.4.20
MySQL version 5.5.32
On another server with older Apache, PHP and MySQL versions multisite WordPress with subdomains is working without any problem.
I have exactly the same problem with same warning. Also a clean WordPress 3.6.1 install without any plugins or custom themes. Multisite and subdomain are enabled.
Also tested with clean 3.5.2 install without any plugins or custom themes and got the same error.

Okay feel really stupid now..
On my header.php I had get_search_form() call inside <form> tag which made the false redirect. Like that:
<form class="searchform">
<?php get_search_form() ?>
</form>
I just removed these tags and everything is working fine.
