ok ok, i got it. Follows a working patch.
Well, the patch is just a hack in my opinion, but.. hey, if there is a
"php_stream_from_zval_no_verify" macro it means you already hacked it
for something..
Maybe i haven't understood the API structure very well yet, but can
php_streams.h access directly zend_fetch_resource() without using a
zend_list.h macro?

Description:
------------
See the example code. It should return FALSE according to the manual
(and to common good sense).
This is causing valid code like
while (($str = fgets($fd)) !== FALSE) {
...
}
to go into infinite loop, which is very bad.
I tried to look at the source code but it looks correct, as it should
fall in file.c:1395, at the exit_failed label.
Reproduce code:
---------------
<?php
$fd = FALSE;
$retval = @fgets($fd);
var_dump($retval);
Expected result:
----------------
FALSE
Actual result:
--------------
NULL
