#32461 [NEW]: MySQL Extension Segmentation Fault

From: nofulfillment at numbinside dot net Operating system: GNU/Linux (Slackware 10.1) PHP version: 5.0.3 PHP Bug Type: MySQL related Bug description: MySQL Extension Segmentation Fault Description: ------------ I'm working with phpMyAdmin (irrelivent, but aids in understanding), and I had the MYSQL_SOCKET file configured wrong. PHP's MySQL extension was creating a Segmentation fault in that it was trying to read a non-existant file. My configure line, I do not believe to be relavent, but I have included it anyways. (Along with some other details from phpinfo()) System: Linux NcFTestServer-Linux 2.4.29-grsec #7 SMP Thu Feb 3 18:41:23 PST 2005 i686 Build Date: Dec 23 2004 15:48:45 Configure Command: './configure' '--prefix=/usr' '--disable-static' '--with-apxs=/usr/sbin/apxs' '--sysconfdir=/etc' '--enable-discard-path' '--with-config-file-path=/etc/apache' '--enable-safe-mode' '--with-openssl' '--with-mhash' '--enable-bcmath' '--with-bz2' '--with-pic' '--enable-calendar' '--enable-ctype' '--with-gdbm' '--with-db3' '--enable-dbase' '--enable-ftp' '--with-iconv' '--with-exif' '--with-gd' '--enable-gd-native-ttf' '--with-jpeg-dir=/usr' '--with-png' '--with-gmp' '--with-mysql' '--with-gettext=shared,/usr' '--with-expat-dir=/usr' '--with-xml' '--enable-wddx' '--with-mm=/usr' '--enable-trans-sid' '--enable-shmop' '--enable-sockets' '--with-regex=php' '--enable-sysvsem' '--enable-sysvshm' '--enable-yp' '--enable-memory-limit' '--with-tsrm-pthreads' '--enable-shared' '--disable-debug' '--with-zlib=/usr' Using php.ini-recommended, although this does NOT change why it's failing (tried falling back to -dist, but had the same problem). GDB backtrace is mostly irrelievent, and it was NOT built with debugging symbols. I believe that this can be solved by checking to see if the file exists. Reproduce code: --------------- Try connecting to MySQL using a non-existant local socket file. (i.e., /tmp/non-exist.sock) Expected result: ---------------- When trying to run phpMyAdmin, I was expecting to see the login page. Actual result: -------------- Output from Bash trying to WGET it to see what happens: user@computer:/# wget http://server/phpMyAdmin_folder/index.php --11:35:05-- http://server/phpMyAdmin_folder/index.php Resolving server... done.
