Output Buffering problem w/ PHP-4.0.5RC2

Making HEAD requests to a page which has had output buffering activated just results in the connection being closed with no response. This makes it pretty unusable. Can anyone else reproduce this problem? Two scripts: nobuffer.php: <? print "hello world!"; ?> buffer.php: <? ob_start(); print "hello buffered world!"; ob_end_flush(); ?> nobuffer.php responds to the GET/HEAD requests fine. buffer.php responds correctly to the GET, but not the HEAD. Transcript is below: [avsm@brick /]$ telnet localhost 80 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'.

I'll upgrade to RC4 in a bit and check if that makes a difference (not seen the ChangeLogs between them yet) (Platform is OpenBSD-2.8-stable). There is nothing in the Apache error log. Anil
