Try configure PHP using the external mysql client libraries:
1. delete config.cache file
2 run your configure with this change:
--with-mysql=/usr (or whatever the install PREFIX is)
Also note: /usr/local/lib or /usr/lib are NOT correct values for any
PHP configure option!! They're /usr/local and /usr

Description:
------------
environment:
apache 2.0.52 in multi-threaded mode
mysql 4.1.11 (and 4.1.6-gamma)
PHP 5.0.4
php configuration:
./configure --with-apxs2=/usr/sbin/apxs \
--with-zlib --enable-calendar \
--with-gd --with-mhash \
--with-xsl --enable-memory-limit \
--prefix=/home/php --with-mysql \
--with-openssl --with-jpeg-dir=/usr/lib \
--with-gettext \
--with-curl=/usr/local/lib
Notes:
* This bug does not occur if I use PHP 5.0.2 in the same environment
instead of PHP 5.0.4.
* It's possible that the fix for bug #31288 is related to this issue.
This code does *not* call the (deprecated) function mysql_list_fields()
at all.
Reproduce code:
---------------
The following code snippet (taken from WordPress wp-includes/wp-db.php,
a blogging program):
while ($i < mysql_num_fields($this->result)) {
$this->col_info[$i] = mysql_fetch_field($this->result);
$i++;
}
Even a single invocation of mysql_fetch_field() will cause the seg.
fault. Nothing is written to the server's error log from PHP itself.
Expected result:
----------------
Code inside a script should not cause a seg. fault.
Actual result:
--------------
When using the code snippet specified, the apache child running the
request seg. faults.
