OpenSSL on the tested computer: Architecture: amd64 , Version:

I can try only on the same server with a different cpu (dual core xeon
and not quad core xeon) and another distro, but not sure when i'll have
time for that, i'll tell you the result here.

I still can not reproduce this on my system.
OpenSSL Version => OpenSSL 0.9.8b 04 May 2006
Are you able to reproduce this on more than one machine? (and with
other linux distro than debian)

Description:
------------
stream_select fails to return the number of modified descriptors.
The bug happen on linux amd64 (tested on a quad core xeon, debian etch
amd64) but not on x86 install (tested on a similar computer but dual
core xeon, debian etch x86).
It seems to happen only when php is built with openssl (i tried many
combinaisons), with php 5.2.0, 5.2.1, 5.2.2, 5.2.3, 5.2.4, php5 snap,
and also php6 snap.
This bug is the same as #40735 but I am unable to modify the status of
that bug.
I can eventually provide a ssh access to the computer further tests and
debug (ask me by email).
Reproduce code:
---------------
<?php
// replace with your smtp ip if needed, need a tcp server which reply
data immediatly
$handle = fsockopen('tcp://smtp',25);
while(!feof($handle)) {
$r = array($handle);
$w = null;
$e = array($handle);
$nb = stream_select($r,$w,$e,3);
echo "select : $nb, r=".count($r).', w='.count($w).',
e='.count($e)."\n";
while($nb>0){
echo "Reading...\n";
$contents = fread($handle,8192);
echo "Contents: [$contents]\n";
$r = array($handle);
$w = null;
$e = array($handle);
$nb = stream_select($r,$w,$e,1);
echo "select : $nb, r=".count($r).', w='.count($w).',
e='.count($e)."\n";
}
usleep(20000);
}
fclose($handle);
?>
Expected result:
----------------
select : 1, r=1, w=0, e=0

Actual result:

select : 0, r=1, w=0, e=0
select : 0, r=1, w=0, e=0
select : 0, r=1, w=0, e=0
select : 0, r=1, w=0, e=0
