Summary: curl hangs on few cases of socks5 connections

Initial Comment:
curl hangs on few cases of socks5 connections. I use
php with libcurl 7.15.3 and I've seen this issue with
some socks servers. I wanted to make system that
tests socks5 servers with curl, however script hanged
on some socks!

I dont know socks protocol so I can say why it is
happening but here is code to recreate:

<?
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL,"http://google.pl");
curl_setopt ($ch, CURLOPT_HEADER, 0);
curl_setopt ($ch, CURLOPT_PROXYTYPE,
CURLPROXY_SOCKS5);
curl_setopt ($ch,
CURLOPT_PROXY, "221.208.173.84:3128");
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt ($ch, CURLOPT_TIMEOUT, 5);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
echo "AAA";
$xyz = curl_exec ($ch);
echo "BBB";
?>

I dont know how log socks under 221.208.173.84:3128
will work as it works now. But for now it causes curl
to hang on curl_exec. Script will show AAA but will
NEVER show BBB. Script wont timeout ever, so it will
break every script.

I've tested september 12 CVS and problem is still there,
however now it timeouts in like 2-4 minutes - you cant set
timeout. Try this one:

<?
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL,"http://google.pl");
curl_setopt ($ch, CURLOPT_HEADER, 0);
curl_setopt ($ch, CURLOPT_PROXYTYPE,
CURLPROXY_SOCKS5);
curl_setopt ($ch,
CURLOPT_PROXY, "202.102.239.179:1080");
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt ($ch, CURLOPT_TIMEOUT, 5);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
echo "AAA";
$xyz = curl_exec ($ch);
echo "BBB";
?>

aditional comment: server under 221.208.173.84:3128 might
not be socks server at all, but this is no reason to curl
not to timeout! It will break every script that for
example want to test socks servers

This is fixed in the current development version, I believe.
Try a daily snapshot or wait for the next release.
