I've ran into some problems with mysql_fetch_object. It segfaults. Used version: php5-200301240830 configure options: './configure' '--with-mysql' '--with-apxs=/usr/local/apache/bin/apxs' Apache error_log: [Sun Jan 26 20:29:03 2003] [notice] child pid 729 exit signal Segmentation fault (11) Afaik a segfault 11 points to a hardware problem but I only get it when I use mysql_fetch_object within PHP5. The function is called within an extended class. Kind regards, Hans Wolters PatchesPull RequestsHistoryAllCommentsChangesGit/SVN commits

K, hear it is: class.Session.php is a session save handler which stores the session data within a database (mysql). As soon as mysql_fetch_objects is used it barfes. This is in both classes and in procedural functions. The code works fine on the same machine when php4.X is used. Let me know if you want more information.
