Can an someone answer me the question, why Version A of this example
won't run???
It's the same behavior on an PHP WinXP CLI or an Ubuntu PHP-CGI/CLI.
Cause I would like to use Version A to setup only once the CurlOpts used
for every call.

<?php
// test case
DEFINE("VERSION","A");
// Version A don't work, the second time fetchData() is called a
// segmentation fault will be raised after some header info recieved.

DEFINE ("VERSION","B");
// works fine.

$kw = new KWExt("http://google.com");

for ($i = 1; $i < 5; $i++)
{
    echo "Round: $i\n";
    $kw->fetchData();
}

class KWExt {
    var $g_targeturl;
    var $c_cookiearr;
    var $ch;
    
    function __construct ($targeturl)
    {
        $this->g_targeturl = $targeturl;
        if (VERSION == "A")
            $this->ch = curl_init(); // Version A
    }
    
    function __destruct()
    {
        if (VERSION == "A")
            curl_close($this->ch); // Version A
    }
    
    function fetchData()
    {
        if (VERSION == "B"){
           $this->ch = curl_init(); // Version B
           $this->_header_callback($this->ch,""); //
        }

        $copts = array (
            CURLOPT_HEADER => 0,
            CURLOPT_HEADERFUNCTION => array($this,'_header_callback'),
            CURLOPT_RETURNTRANSFER => 1,
            CURLOPT_VERBOSE => 1
        );
        
        curl_setopt($this->ch, CURLOPT_URL, $this->g_targeturl);
        
        curl_setopt_array($this->ch,$copts);
        $out = curl_exec($this->ch);
        
        if (VERSION == "B")
            curl_close($this->ch); // Version B
    }
    
    function _header_callback($ch, $string)
    { // from php.net
        $length = strlen($string);
        if(!strncmp($string, "Location:", 9))
        { #keep track of last redirect
          $location = trim(substr($string, 9, -1));
        }
        
        if(!strncmp($string, "Set-Cookie:", 11))
        { #get the cookie
          $cookiestr = trim(substr($string, 11, -1));
          $cookie = explode(';', $cookiestr);
          $cookie = explode('=', $cookie[0]);
          $cookiename = trim(array_shift($cookie));
          $this->c_cookiearr[$cookiename] = trim(implode('=', $cookie));
        }
        
        $cookie = "";
        if(trim($string) == "")
        { #execute only at end of header
          foreach ($this->c_cookiearr as $key=>$value)
          {
            $cookie .= "$key=$value; ";
          }
            curl_setopt($ch, CURLOPT_COOKIE, $cookie);
        }
        return $length;
    }
}
