PHP Bug Type: *General Issues
Bug description: stream_select

Description:
------------
hello i was using archlinux 32 bits version on pentium3
i bought an intel core 2 duo e6600 and i'm using archlinux 64
my code on 32 bits was using

$read = array($stream);
if (false === ($num_changed_streams = stream_select($read, $write = NULL,
$except = NULL, 1,0))){

on 32 bits ok, it wait one second or if data received return with
num_changed_stream>0

on 64 bits no, it return imediatly and num_changed_stream=0, since tcpdump
didn't show nothing i think that's an 64bits bug

i created $stream with:

$stream = stream_socket_client("tcp://172.16.0.1:515", $this->errNo,
$this->errStr, $this->timeout);
stream_set_write_buffer($stream,0);
stream_set_blocking($stream,1);
stream_set_timeout($stream,2,0);



Reproduce code:
---------------
<?
$stream = stream_socket_client("tcp://172.16.0.1:515", $this->errNo,
$this->errStr, $this->timeout);
stream_set_write_buffer($stream,0);
stream_set_blocking($stream,1);
stream_set_timeout($stream,2,0);

$read = array($stream);
echo microtime(0)."\n";
$num_changed_streams = stream_select($read, $write = NULL, $except = NULL,
1,0);
echo microtime(0)."\n";

?>

Expected result:
----------------
a long time (1 second of diff)

Actual result:
--------------
on 32bits php ok
on 64 bits php return .0010 seconds of diff and tcpdump didn't showed
nothing on this stream

New Comment:

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.
