Adam, this bug report is related to sending files to the client and
doesn't seem
to be related to variable types. I don't think this is a dup of #44522.
The interesting stuff can be found at

Description:
------------
Something in PHP5 running under apache2 under Ubuntu 9.10 is not fully
64 bit
aware on a 64 bit system. PHP scripts run under Apache correctly under
Ubuntu
8.04 (PHP 5.2.4). Under Ubuntu 9.10 (PHP 5.2.10) and 10.04 (PHP 5.3.2),
some
place a value is being treated as 32 bits on a 64 bit system and is
wrapping
instead of using full 64 bits. Related to sending large data (> 4G) in
response
to an HTTP post request.
Did not test with Ubuntu 8.10 or 9.04 - both PHP 5.2.6.
What happens: Data aborts based on wrap. Calculated number of bytes to
be served
are correct (>4G) as listed in the HTTP length header. Actual bytes
served are
(size) && 0xFFFFFFFF instead of (size) && 0xFFFFFFFFFFFFFFFF on 64 bit
system.
Most of data is being transfered via fpassthru($openFileHandle) call,
providing
>4G bytes of data.
Test script:
---------------
<?php
header("Connection: close");
// NOTE: File test.txt needs to be more than 2^32 bytes. Pick a large
file, over 0x100000000 bytes
// in size, such as
http://cdimage.debian.org/debian-cd/5.0.4/amd64/iso-dvd/debian-504-amd64-DVD-1.iso
$name = "/var/www/test.txt";
$fs = filesize($name);
$fp = fopen($name,'rb');
$httpByteLen = $fs;
header("Connection: close");
header("Content-Type: application/octet-stream");
header("Content-Length: " . $httpByteLen);
header("HTTP/1.1 200 OK");
set_time_limit(0);
fpassthru($fp);
exit;
?>
Expected result:
----------------
The entire ISO file to be downloaded.
Actual result:
--------------
Tested using the test script (attached), and using the suggested debian
dvd .iso
image as the input file. The ISO is 4,697,126,912 bytes. Download
socket is
closed after 402,159,616 bytes, which again is the file size &
0xFFFFFFFF.
