curl_exec crashes, when there's a CURL_WRITEHEADER set. it didn't use to when using php 4.0.4pl1 and curl 7.7.2. In PHP 4.0.6 it crashes with both curl 7.8.1 and 7.9.1.

my config line:

./configure -enable-debug --with-openssl --enable-bcmath --enable-calendar --with-curl --with-dom=/usr/local --enable-ftp --enable-gd-imgstrttf --with-gd --with-jpeg-dir=/usr/local --with-mysql=/usr/local --enable-sockets --with-swf --with-zlib --enable-inline-optimization --enable-track-vars --with-ttf --with-freetype

(it also crashes when used as apache 1.3.22 module)


script:

<?

$host="www.php.net";
$uri="/search.php";

$conn=curl_init("http://".$host.$uri);

$file1=fopen("/tmp/headers.txt", "w");
$file2=fopen("/tmp/content.txt", "w");

// if you comment the next line, everything is ok (but then you have no headers :(
curl_setopt($conn, CURLOPT_WRITEHEADER, $file1);
curl_setopt($conn, CURLOPT_FILE, $file2);

curl_exec($conn);
curl_close($conn);

fclose($file1);
fclose($file2);

?>
