Bug description: Segmentation Fault when using MySQL
Description:
------------
OK Guys. I'm a Windows man with little experience of UNIX type
environments, but I will try to give you as much information as possible.
I am running PHP 5.0.2 compiled with MySQL 4.1.5(gamma) as so:
./configure --with-apxs --enable-calendar --enable-sockets --with-gd
--with-gd-dir=/usr/local/include --enable-gd-native-ttf --with-freetype
--with-freetype-dir=/usr/local/include/freetype2 --with-jpeg
--with-jpeg-dir=/usr/local/include --with-zlib
--with-zlib-dir=/usr/local/include --without-png
--with-mysql=/usr/local/lib/mysql --enable-debug
The MySQL client libraries are the same version as the server. I'm also
using Apache 1.3 if that's relevant.
All my PHP scripts using MySQL work as expected. However, when I try
browsing for data using phpMyAdmin, I get an empty document. Apache
reports a segmentation fault.
>From all the evidence, including the bt, this all seems very similar to
bug #26208, but I am running a version of MySQL which should have fixed
the problem.
I am sure there's plenty more information you need from me. Tell me what
you need, and I will try to provide it.
Reproduce code:
---------------
Apologies, but phpMyAdmin has some massive libraries I don't really want
to sift through. Just try browsing a table with any version of phpMyAdmin
(I have tried quite a few before I traced the problem to a segmentation
fault).
If you really need the code, I will try and sort through all the script
and distill it into a few lines :(
Expected result:
----------------
The contents of a table should be displayed, but seg fault occurs as
described
Actual result:
--------------
