ID: 42650 Updated by: [EMAIL PROTECTED] Reported By: gordonthree at gmail dot com -Status: Open +Status: Feedback Bug Type: ODBC related Operating System: Centos 5 PHP Version: 5CVS-2007-09-13 (CVS) 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 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 you please compile PHP with --enable-debug and try running the script on the command line. The backtrace should be much better then the one you currently have. From the current backtrace it does not appear that the crash is inside PHP.

(try search for existing reports about using odbc_pconnect(), there are open bug reports about it crashing already..) ------------------------------------------------------------------------ [2007-09-13 04:03:00] gordonthree at gmail dot com sorry, it looks like the trace I provided was not for the worker that actually died. any tips on how to determine what httpd worker thread to attach to, to capture it dieing? ------------------------------------------------------------------------ [2007-09-13 03:59:09] gordonthree at gmail dot com Description: ------------ When attempting to connect to an odbc data source via odbc_pconnect with incorrect username and/or password, the httpd (apache) instance handling that connection segfaults. OS is Centos 5 (RHEL5) running in a vmware server virtual machine 32 bit I am using ODBC to connect to a mysql server running on localhost for persistent db connections and mysql stored proc support. Reproduce code: --------------- <HTML><BODY> <?php $link_id = odbc_pconnect('Default', 'root','badpassword'); if(!$link_id){die("no connection!");} else{echo "connected";} ?> </BODY></HTML> Expected result: ---------------- user should see connected printed on web page.
