#24399 [Com]: PEAR DB isError crash [instanceof_function fault?]

ID: 24399 Comment by: fep at cs dot uiuc dot edu Reported By: mattmichalowski at hotmail dot com Status: Closed Bug Type: PEAR related Operating System: Linux (i686 2.2.15) PHP Version: 5.0.0b1 (beta1) New Comment: Having a problem with PHP5 RC3 experiencing a segmentation fault that is very similar to this reported bug fixed last year. A simple PEAR DB test script causes a segfault. Our environment is very similar to the one listed below except we are using an Oracle database client against an Oracle 10G database server.
