Ran the following script which uses curl to download file from a remote web server:

<?php
$ch = curl_init();
echo "Downloading....\n";
curl_setopt($ch, CURLOPT_TIMEOUT, '600');
curl_setopt($ch, CURLOPT_URL, "http://downloads.sourceforge.net/freeghost/Kernel-2.6.32.1.kitchensink" );
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt( $ch, CURLOPT_BINARYTRANSFER, 1 );
$fp = fopen("/tmp/bzImage", 'wb');
if ( $fp )
{
	curl_setopt($ch, CURLOPT_FILE, $fp);
	curl_exec ($ch);
	curl_close ($ch);
	fclose($fp);	
}			

for( $i = 0; $i < 3; $i++ )
{
	echo filesize( "/tmp/bzImage" ) . "\n";
	sleep( 10 );
}
?>


Expected:

file size to report the real size of 4142832 bytes

using 
 
ls -l 

during the running of the script (before it terminates) returns a
filesize of 4141056 but it should return 4142832 as it does when the
script exits.

This was confirmed on two desktops, and functions correctly on Fedora 9

This is a problem is you are chain operations in the same script,
because it appears as if the file doesn't get flushed to disk.  So for
example, we attempt to ftp the file off after download, but it is
corrupted as only 4141056 bytes are sent.

Thanks in advance for any help you can provide.
