#50727 [NEW]: Accesing mysqli->affected_rows on no connection causes segfault

From: lodeclaassen at gmail dot com Operating system: Debian Linux PHP version: 5.2.12 PHP Bug Type: Reproducible crash 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 -- Edit bug report at http://bugs.php.net/?id=50727&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=50727&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=50727&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=50727&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=50727&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=50727&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=50727&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=50727&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=50727&r=needscript Try newer version: http://bugs.php.net/fix.php?id=50727&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=50727&r=support Expected behavior: http://bugs.php.net/fix.php?id=50727&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=50727&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=50727&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=50727&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=50727&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=50727&r=dst IIS Stability: http://bugs.php.net/fix.php?id=50727&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=50727&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=50727&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=50727&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=50727&r=mysqlcfg
