From: marcing at smlw dot pl Operating system: WinXP SP2 PHP version: 5.1.0 PHP Bug Type: MySQLi related Bug description: using mysqli with MySQL 5.0.16 causes Apache crash Description: ------------ Env: Windows XP SP2 Apache 2.0.48 / 2.0.55 (not relevant) MySQL 5.0.16 PHP 5.0.3 /5.1 (not relevant) MySQLi Important: Problem is related to MySQLi when using MySQL version 5 only, it doesn't occur with version 4. Reproduce code: --------------- <?php $db = new mysqli(...); if($stmt = $db->prepare('SELECT SUM(visitors) FROM core_stats')) { $stmt->execute(); $stmt->bind_result($total); $stmt->close(); } ?> The problem occurs when using SUM() in query, endless loop seems to start when $stmt->bind_result($total) is invoked and as a result Apache crashes. Database reproduction code: ---------------------------------- CREATE TABLE core_stats ( id int(10) unsigned NOT NULL auto_increment, day_of_week int(1) unsigned NOT NULL default '0', day_of_month int(2) unsigned NOT NULL default '0', m int(2) unsigned NOT NULL default '0', y int(4) unsigned NOT NULL default '0', visitors int(10) unsigned NOT NULL default '0', PRIMARY KEY (id) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; INSERT INTO core_stats VALUES (1, 2, 5, 7, 2005, 1); INSERT INTO core_stats VALUES (2, 3, 6, 7, 2005, 6); INSERT INTO core_stats VALUES (3, 4, 7, 7, 2005, 7); INSERT INTO core_stats VALUES (4, 5, 8, 7, 2005, 1); Expected result: ---------------- It should work as it worked on MySQL 4.
