#45933 [Opn]: Segfault var_dump PDOStatement Obj with die

ID: 45933 User updated by: alexc223 at googlemail dot com -Summary: Segfault var_dumo PDOStatement Obj with die Reported By: alexc223 at googlemail dot com Status: Open Bug Type: PDO related Operating System: Arch Linux PHP Version: 5.2.6 New Comment: This line: $pdo_st = $sql->prepare( 'SELECT * FROM foobar' ); Should read: $pdo_st = $sql->prepare( 'SELECT * FROM foobar WHERE zomg = :zomg' ); However, both still produce a segfault. Previous Comments: ------------------------------------------------------------------------ [2008-08-27 11:02:20] alexc223 at googlemail dot com Description: ------------ Attempting to 'var_dump' a PDOStatement object within a function, and then calling 'die' using PDO_MYSQL. MySQL query at the top is just incase you need to test it with that to, though I can re-produce this with any table and MySQL database. Reproduce code: --------------- CREATE TABLE foobar ( zomg varchar(255) NOT NULL, KEY zomg (zomg) ) TYPE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci; <?php function foo( $bar ) { var_dump( $bar ); // Removing the following line stops the segfault from happening die; } $sql = new PDO( 'mysql:host=localhost;dbname=DATABASE', 'USER', 'PASS' ); $pdo_st = $sql->prepare( 'SELECT * FROM foobar' ); foo( $pdo_st ); ?> Expected result: ---------------- object(PDOStatement)#2 (1) { ["queryString"]=> string(39) "SELECT * FROM foobar WHERE zomg = :zomg" } Actual result: -------------- Output from gdb (unable to enable debug within PHP) Program received signal SIGSEGV, Segmentation fault.
