Allowing ssh access to my machine will require me to request a
firewall change which may take some time. However, I have found this
behavior only presents itself when PHP is compiled with
the --with-curlwrappers option. Explicitly disabling this option
returns my machine to the expected behavior. Cheers!

What information can I provide to help determine the cause of this
problem on my system? Thanks!

Description:
Since php 5.2.0 stream_select fails to return the number of modified
descriptors on a 64bit Linux OS (32bit seems to be immune to this).
Verified to exist in the php-snap php5.2-200703052130.
This bug is the same as #40458 but I am unable to modify the status of
that bug.
Reproduce code:
---
?php
$sock = stream_socket_client('tcp://maila.microsoft.com:25', $eno,
$estr, 10, STREAM_CLIENT_CONNECT);
stream_set_blocking($sock, 0);
sleep(1);
$r = $w = array($sock);
$n = stream_select($r, $w, $e = NULL, 10);
echo Selected: {$n}\n;
echo Read: , print_r($r,1);
echo Write: , print_r($w,1);
?
Expected result:
Selected: 2
Read: Array
(
[0] = Resource id #5
)
Write: Array
(
[0] = Resource id #5
)
Actual result:
--
Selected: 0
Read: Array
(
[0] = Resource id #5
)
