Duplicate of bug #37445. Previous Comments: ------------------------------------------------------------------------ [2006-07-24 15:39:42] jerome at macsaresexy dot com This is from within my application, seems I actually couldn't crash it with the simplified case I posted, but will if I use that simple class test from within my application (which loads many things in a common file including the PDO connection) This is the backtrace when it happens: Program received signal SIGSEGV, Segmentation fault.

To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php for *NIX and http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32 Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. Can't reproduce. ------------------------------------------------------------------------ [2006-07-20 17:41:39] jerome at macsaresexy dot com Description: ------------ PHP crashes with a seg fault if you try to call a method that doesn't exist, on any particular object, after a call from PDO::prepare() or PDO::query(). Reproduce code: --------------- class TestClass { static $db; function test() { $stmt = self::$db->prepare('SELECT * FROM users'); $this->omg(); } } TestClass::$db = new PDO('mysql:host=localhost;dbname=mydb','root',''); $test = new TestClass(); $test->test(); Expected result: ---------------- Should produce a call to undefined method TestClass::omg() fatal error message. Actual result: -------------- What I get instead is a segmentation fault of the child apache process seen in the error_log file. This only happens when $db->prepare() is assigned to a variable too, if $stmt = isn't there, it won't crash. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=38166&edit=1
