Bug description: ob_get_length() returns incorrect value
Description:
------------
Very straightforward.
I have a preamble and postamble include on ALL of my main .php pages...
which use ADODB session management, some PEAR, and other typical dynaweb
goodies.
The Content-Length header is *ALWAYS* off by about 81 bytes, as in, the
ob_get_length() is always smaller than the actual size of the content
sent...
I've verified this with "netcat" - after trimming the headers from the
reply, the content is 81 bytes larger than advertised in the
Content-Length header.
I observed no change in behaviour after adding the ob_clean() call into my
header file.
OTHERWISE, things work fine.
What's the deal? Is Apache silently adding CRLF's?
I am NOT using the gzhandler or transparent compression here. This is
just straightforward output.

Reproduce code:
---------------
The code for all of my index.php's consist of the following:
<?PHP
include_once 'db_header.inc';
................
include_once 'db_footer.inc';
?>
db_header.inc:
<?php
$start_time=gettimeofday();
ob_clean(); // paranoid and desperate
ob_start();
header("Connection-Type: Keep-Alive");
?>
db_footer.inc contains:
<?PHP
if ($LOGGING)
{
$LOG->close();
$LOGGING=FALSE;
}
header('Content-Length: ' . ob_get_length());
ob_end_flush();
?>
Note: there are no blank lines at the beginning of my *.inc or *.php
files.
Expected result:
----------------
I would expect Content-Length to reflect the actual output size.
