Status: Open Type: Bug Package: MySQLi related Operating System: Mac OS X 10.6.7 PHP Version: Irrelevant Block user comment: N Private report: N New Comment: try it on 5.3.3, or is it meaningless? Previous Comments: ------------------------------------------------------------------------ [2011-07-03 10:29:59] felipe@php.net I can't reproduce it on 5.4. ------------------------------------------------------------------------ [2011-07-03 00:06:14] 1000235409 at smail dot shnu dot edu dot cn I cannot generate a backtrace since I am not willing to mess up machine, and there is no possibility to install a virtual machine because I haven't a OS X Server installation DVD, So, is it possible to solve this bug without providing a backtrace? ------------------------------------------------------------------------ [2011-07-01 11:48:16] aharvey@php.net Thank you for this bug report. To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php for *NIX and http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32 Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. ------------------------------------------------------------------------ [2011-07-01 11:25:54] 1000235409 at smail dot shnu dot edu dot cn Description: ------------ Calling mysqli::get_attr() under Mac OS X always leads php to crash with exit code 139, even after receiving true with calling mysqli::set_attr() before. 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
