Proved under PHP-CGI 5.3.3 with MySQL 5.1.44. This situation will not happen under Windows and Linux (at least Ubuntu 10.10). Test script: --------------- $conn=new mysqli('localhost', 'root', '', 'test', 3306, '/Applications/XAMPP/xamppfiles/var/mysql/mysql.sock'); $stmt=$conn->stmt_init(); $stmt->prepare('select 1+1'); $a=$stmt->attr_set(MYSQLI_STMT_ATTR_CURSOR_TYPE,MYSQLI_CURSOR_TYPE_READ_ONLY); var_dump($a); //true $stmt->attr_get(MYSQLI_STMT_ATTR_CURSOR_TYPE); //php crashed with exit value 139. $stmt->execute(); echo $stmt->attr_get(MYSQLI_STMT_ATTR_CURSOR_TYPE);// ...or, put that code here, and the same problem happens. echo 'SUCC'; Expected result: ---------------- SUCC Actual result: -------------- *SIMPLY CRASHED* ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55104&edit=1
