Description:
------------
The issue:
when I load a php file in a browser that references
mysql, it crashes the apache thread.
The clues:
if I call the same php from the command line, it works
perfectly!
If I call a php file that doesn't use mysql, it works
perfectly!
The problem is only when calling a php file using mysql
THROUGH A BROWSER.
The environment
slackware with kernel 2.6.11.8
php 5.1.2
apache 2.2.0
mysql 4.1.18 (pre-compiled downloaded from mysql.com)
apache config command:
./configure --with-apr=/usr/local/apr-httpd/ --with-apr-
util=/usr/local/apr-util-httpd/ --enable-so --enab
le-rewrite --disable-autoindex --enable-ssl --with-ssl=/usr/
local/ssl
php config command:
'./configure' '--with-apxs2=/usr/local/apache2/bin/apxs' '--
with-mysql=/usr/local/mysql' '--with-mysql-sock=/tmp/
mysql.sock' '--with-sqlite' '--enable-sqlite-utf8' '--with-
zlib' '--with-zlib-dir' '--with-bz2' '--with-gd' '--enable-
gd' '--enable-gd-native-ttf' '--with-jpeg-dir=/usr/local'
'--with-png-dir=/usr/local' '--with-ttf' '--with-curl=/usr/
local' '--enable-track-vars' '--with-gettext' '--with-
config-file-path=/usr/local/apache2/conf' '--enable-trans-
id' '--enable-ftp' '--enable-mbstring' '--with-openssl=/usr/
local/ssl'
Reproduce code:
---------------
Any code tht calls a mysql connection.
Expected result:
----------------
The apache thread that handles this request dies with a
segmentation fault
php filname.php - WORKS PERFECTLY
http://server.com/filename.php - CRASHES
Actual result:
