Here is a simple code for this : 
<?php
curl_setopt($ch, CURLOPT_URL, "ftp.dds.be"); // this is an 
example
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt ($ch, CURLOPT_HEADER, 1);
curl_setopt ($ch, CURLOPT_NOBODY, 1);
curl_setopt ($ch, CURLOPT_TIMEOUT, 5);

print "OK until now\n";
var_dump( $retour = curl_exec ($ch));
?>

When the protocol is not specified, and the host name 
starts with ftp., there is a conflict segfault.
It seems to have a conflict where curl choose automatically 
ftp protocole for ftp.*.* sites, but the script ask for 
http header. Then php crashes.

This has been found with PHP 4.1.0/4.1.1 for windows, and 
PHP 4.1.2/ curl 7.9.4

PHP should return an error, but not crash. Note that when 
specifying the protocol, (eg, "http://ftp.site.com"), it 
works fine.

This bug has been fixed in CVS. You can grab a snapshot of the

problem, the fix will show up soon at http://www.php.net/manual/.
In case this was a PHP.net website problem, the change will show

Thank you for the report, and for helping us make PHP better.

Markus, Honey,

I tried this baby with PHP 4.3.0 (21rst july snapshot) on 
MacOSX, and it is now closed. Good job.
