I've just noticed the version problem in the curl line above even tho they're all fresh compiles. It may bea curl bug but I'll file here just in case.

Script is in SOAP/Client.php in PEAR repository. Running test scropt also in the repository causes segfault either in http or https

Relevant code is:
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: text/xml"));
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_FAILONERROR, 1); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 
curl_setopt($ch, CURLOPT_USERAGENT, $this->_userAgent);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); 
curl_setopt($ch, CURLOPT_VERBOSE,1); 
curl_setopt($ch, CURLOPT_POST, 1);
$result=curl_exec ($ch); 
curl_close ($ch);
