PHP Version: 5.0.2

New Comment:
Even if the wrong client library is used, it should not
crashed. Discussed this with my MySQL colleagues before,
probably we have to change the FIELD structure to provide
BC.
Changing Status to assigned - not sure if a possible fix
will go in to ext/mysql or libmysql

Sorted. Apologies. Wrong client library linked in. PHP is blameless.

Hi Georg. Thanks for your quick response.
I don't think the table structure is that important. This error occurs
on all tables of different types, on a wide variety of different dbs.
Executing SHOW CREATE TABLE commands via phpMyAdmin causes the seg
fault again, but if you really want an example of one of my tables, I
can get one or two definitions directly via the mysql prompt.
Cheers

Looks like some BC break in MYSQL_FIELD structure inside
libmysql.
Could please also provide the table definition (SHOW
CREATE TABLE) ?

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:
