When calling curl_exec twice with RETURNTRANSFER option there's a (reproductible) core dump. Here's a test case :

$ch=curl_init();
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_URL,'http://www.yahoo.com');
curl_exec($ch);
echo('this text is displayed');
curl_exec($ch);
echo('this text is not displayed (core dump instead)');

The problem shows up in 4.1.0RC1 AND 4.1.0RC2 (but not 4.0.6). If you remove the RETURNTRANSFER option then it works fine. I'm affraid I don't have the knowledge to compile a debug version and give more infos.

Forgot the compile options :

 './configure' '--with-gd=/usr/home/domi4/src/gd-1.8.4' '--enable-exif' '--with-jpeg-dir=/usr/local' '--with-png-dir=/usr/local' '--enable-gd-native-ttf' '--with-mysql=/usr/local' '--disable-pear' '--with-config-file-path=/usr/home/domi4/etc' '--enable-debug=no' '--enable-force-cgi-redirect=yes' '--with-zlib' '--with-openssl=/usr/local/ssl' '--with-curl=/usr/home/domi4/src/curl-7.9' '--with-dom=/usr/home/domi4/'
