#35435 [Fbk]: PDO::query is not returning a PDOStatement object

ID: 35435 Updated by: wez@php.net Reported By: bugs at jth dot net Status: Feedback Bug Type: Reproducible crash Operating System: Linux Fedora 3 PHP Version: 5.1.0 New Comment: Thank you for this bug report. 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 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. You have no error handling code in your script. Try also setting this before issuing queries: $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); If you're getting segfaults, we need a backtrace. Try the latest snapshot, and please provide us with a backtrace.
