You can't reuse the same handle... ------------------------------------------------------------------------ [2002-08-27 14:22:23] sniper@php.net Got the same results.. ------------------------------------------------------------------------ [2002-08-27 04:11:19] papier@sdv.fr It seems that bug #14142 is back. This simple exemple generate a Segmentation fault. The bug occurs only when RETURNTRANSFER is set and when using 2 curl_exec on the same curl handle. Changing the 2nd URL to http://www.php.net/ generate an infinite loop ! <? $ch = curl_init(); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch,CURLOPT_URL,"http://www.apple.com/"); $res1 = curl_exec($ch); curl_setopt($ch,CURLOPT_URL,"http://www.apple.com/quicktime/"); $res2 = curl_exec($ch); curl_close($ch); ?> PHP 4.2.2 / libcurl 7.9.8 and './configure --with-curl'.
