PHP Bug Type: MySQL related
Bug description: Segmentation fault (11)
Description:
------------
When runing the sample PHP/MySQL connection script from the documentation
the error.log file displays :
[Sat Mar 27 10:11:47 2004] [notice] child pid 17417 exit signal
Segmentation fault (11)
The same script run from the command line produces a simple:
Segmentation fault
I upgraded my MySQL database to 4.0.18 from a 3.0 release.
My configure options for php:
'./configure' \
'--with-mysql=/usr/local/mysql/' \
'--with-apxs2=/var/lib/apache/sbin/apxs' \
'--disable-debug' \
'--enable-pic' \
'--enable-inline-optimization' \
'--with-zlib=shared' \
'--with-zlib-dir=/usr' \
'--enable-magic-quotes' \
'--enable-track-vars' \
'--with-regex=system' \
'--with-mod_charset' \
'--enable-force-cgi-redirect' \
'--with-openssl=/usr/local/ssl/' \
'--with-bz2=/usr' \
'--with-jpeg-dir=/usr' \
'--with-inifile' \
'--with-tidy' \
'--with-curl=/usr/local' \
'--with-flatfile' \
'--with-png-dir=/usr' \
'--with-gd' \
'--with-ttf' \
'--enable-gd-native-ttf' \
'--with-freetype-dir=/usr' \
'--with-gmp' \
'--with-mhash' \
'--enable-dba' \
'--with-db4=/usr/local/BerkeleyDB.4.2/' \
'--with-mcrypt'
My MySQL configure options:
CFLAGS="-O3" CXX=gcc CXXFLAGS="-O3 -felide-constructors \
-fno-exceptions -fno-rtti" ./configure \
--prefix=/usr/local/mysql --enable-assembler \
--with-mysqld-ldflags=-all-static
Reproduce code:
---------------
<?php
$link = mysql_connect("localhost", "kevenden", "some_password")
or die("Could not connect: " . mysql_error());
echo "Connected successfully";
mysql_close($link);
?>
Expected result:
----------------
Connected successfully
Actual result:
--------------
