Description:
------------
This is exactly the same as bug #28933, except it's still happening for me on PHP 5.0.3 on x86_64.  I would have added a comment to that bug but it's been closed.

The only other info I've seen on the net related to this is something about mixing 32-bit and 64-bit libraries.  I'm running a pure 64-bit system so that's not the problem.

I tested this with the simplest possible configuration: "./configure --with-mysqli=/usr/bin/mysql_config" and ran the test script (functionally identical with the one in #28933) with the CLI version, using php.ini-dist.

Tested with mysql versions 4.1.7 and 4.1.10.

Reproduce code:
---------------
See bug #28933

Expected result:
----------------
PHP to not segfault :)

Actual result:
--------------
PHP segfaults :(

My apologies, I should have tried a cvs snapshot before submitting the bug report.

Still segfaults with 5.0.4.  Is there anything else I can do to help you guys figure this out?  An account on my system or something?
