Bug description: Accesing mysqli->affected_rows on no connection causes
segfault
Description:
------------
I open a mysqli connection that failes (in the tested case wrong
password). After that when I try to get the affected rows
(mysqli->affected_rows) PHP exits and I only get a blank screen.
The configure command from phpinfo:
'./configure' '--with-apxs2' '--with-curl=/usr/local/lib' '--with-gd'
'--enable-gd-native-ttf' '--with-ttf' '--with-gettext'
'--with-jpeg-dir=/usr/local/lib' '--with-freetype-dir=/usr/local/lib'
'--with-kerberos' '--with-openssl' '--with-mcrypt' '--with-mhash'
'--with-mysql=/usr/local/mysql'
'--with-mysqli=/usr/local/mysql/bin/mysql_config'
'--with-pdo-mysql=/usr/local/mysql' '--with-pear'
'--with-png-dir=/usr/local/lib' '--with-zlib'
'--with-zlib-dir=/usr/local/lib' '--enable-zip' '--with-iconv=/usr/local'
'--enable-bcmath' '--enable-calendar' '--enable-ftp'
'--enable-magic-quotes' '--enable-sockets' '--enable-mbstring'
Other settings I don't know, I don't operate the host.
Reproduce code:
---------------
<?php
echo 'startup<br />';
if (isset($_GET['try']) && $_GET['try'] == 1) {
$connection = new mysqli('localhost', 'user', 'wrong password',
'SomeExistingTable');
$connection->query("SELECT `id` FROM `SomeExistingTable` LIMIT 1");
echo 'affected rows: '.$connection->affected_rows.'<br />';
}
echo 'ending<br />';
?>
Expected result:
----------------
If I request the file with ?try=0 I expect:
startup
ending
When I request ?try=1 I get nothing, a blank screen.
Actual result:
--------------
With ?try=1 I expect to see:
startup
affected rows:
ending
