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?

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.

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*
