When executing the following code:

<?php

  echo "Starting...<BR>\n";

  $dba = dba_open("./test.db", "r", "ndbm");

?>

The following error message is encountered:

Warning: driver initialization failed in /var/www/devuser/devbox-mx.dhs.org/www/test/test.php on line 5

PHP 4.2.0 was compiled with the following command:

'./configure' '--with-apxs=/usr/sbin/apxs' '--with-mysql' '--with-pgsql' '--with-config-file-path=/etc' '--enable-track-vars' '--disable-short-tags' '--disable-posix' '--with-curl' '--with-gettext' '--with-ldap' '--with-zlib' '--with-dom' '--with-db' '--with-gdbm=/usr/include/gdbm' '--with-ndbm=/usr/include/db1' '--with-db2=/usr/include/db2' '--with-db3=/usr/include/db3'

The problem has further degraded...

Insteading getting a PHP warning about driver init failure, the page fails to load, and I am getting all kinds of these messages in HTTPD's error_log that read:

[notice] child pid [PID] exit signal Segmentation fault (11)

I'm convinced that this is a problem with PHP.

Note the the above error (segfault) is encountered when the following code is executed:

$dba = dba_open("./test.db", "r", "db2");

So the segfault is related to a different driver set
