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:
