I should also add that the workaround (that works for this example
file) does not always work.

Also tried with the latest CVS snapshot of 5.2.7-dev and it still gives
incorrect results.

Tested this with PHP v5.2.6 on Windows 2008 Server and FreeBSD 7.0 and
it still returns incorrect results.

Using:

PHP 5.2.6RC4-dev (cli) (built: Apr  2 2008 08:04:44)

Still i get the faulty output:

Description:
------------
On some occasions stream_get_line acts weired by attempting the first
seek without considering the "end of line" string.

Below is the sample code that shows the problem with a workaround to
temporarily solve the issue (that might ring some bells for the person
who plans on fixing this).

The code uses a small binary JPX file that can be fetched from
http://barahmand.com/streambug/sample.txt

Reproduce code:
---------------
<?php 
$filename = 'sample.txt';
$arr = explode('<EndOfFrame>', file_get_contents($filename));
echo "Found in source at ".strlen($arr[0])."\n\n";
$fp = fopen($filename, "rb");
stream_get_line($fp, 15000, "<EndOfFrame>");
echo "Location in stream: ".ftell($fp)."\n";
echo "Rewinding...\n"; rewind($fp);
stream_get_line($fp, 15000, "<EndOfFrame>");
echo "Location in stream: ".ftell($fp)."\n";
rewind($fp);
echo "\nAttempting fix...\n";
stream_get_line($fp, 1, "<EndOfFrame>");
stream_get_line($fp, 15000, "<EndOfFrame>");
echo "Location in stream: ".ftell($fp)."\n";
echo "Rewinding...\n"; rewind($fp);
stream_get_line($fp, 15000, "<EndOfFrame>");
echo "Location in stream: ".ftell($fp)."\n";
fclose($fp);
?>

Expected result:
----------------
Found in source at 9295

Location in stream: 9307
Rewinding...
Location in stream: 9307

Attempting fix...
Location in stream: 9307
Rewinding...
Location in stream: 9307

Actual result:
--------------
Found in source at 9295

Location in stream: 15000
Rewinding...
Location in stream: 15000

Attempting fix...
Location in stream: 9307
Rewinding...
Location in stream: 9307
