I can confirm this bug (on Ubuntu using PHP 5.2.10-2ubuntu6.5 with Suhosin-Patch
0.9.7 (cli) (built: May 21 2010 06:30:21) )
Here is a workaround function I made that seems to work:
function stream_get_line_fixed($handle, $length, $ending) {
// Only allow 3 tries since if there's a genuine failure we don't want to
loop forever
$tries = 3;
$ret = FALSE;
while ($ret === FALSE && $tries--) {
$ret = stream_get_line($handle, $length, $ending);
}
return $ret;
}

This is reproduceable on Linux too.

Description:
------------
When use in combination of stream_get_line and fseek,
reading a file which has only 2 lines without ending on EOF(like below) does fail.
This happens on only Windows and with only "2lines file without ending on EOF".
Reproduce code:
---------------
2lines.txt
--
a<CRLF>
b<EOF>
phpfile:
--
<?php
$file = dirname(__FILE__) . '/2lines.txt';
$fp = fopen($file, "rb");
var_dump(stream_get_line($fp, null, "\xd\xa"));
fseek($fp, ftell($fp)); // expected that this does not affect result.
var_dump(stream_get_line($fp, null, "\xd\xa"));
Expected result:
----------------
string(1) "a"
string(1) "b"
Actual result:
--------------
string(1) "a"
bool(false)
