Description:
------------
segmentation fault when connecting to db.
This happens only on our production server, not on my development machine (debian, php 4.3.3RC3). Both use latest DataObject version.

Using exit(); at several points I found the offending line in function _connect():
// it's not currently connected!
// try and work out what to use for the dsn !

$options= &$_DB_DATAOBJECT['CONFIG'];
$dsn = @$this->_database_dsn;

if (!$dsn) {
if (!$this->_database) {
#Offending line############
$this->_database = @$options["table_{$this->__table}"];
######################
}
if (@$this->_database && @$options["database_{$this->_database}"]) {
$dsn = $options["database_{$this->_database}"];
} else if ($options['database']) {
$dsn = $options['database'];
}
}

Reproduce code:
---------------
This is a dump of the $options
array(17) {
["dont_die"]=>
string(1) "0"
["database"]=>
string(29) "mysql://root@localhost/websms"
["#schema_location"]=>
string(15) "../../../../etc"
["schema_location"]=>
string(35) "/home/sta01/www/testsite/etc/websms"
["class_location"]=>
string(9) "generated"
["require_prefix"]=>
string(12) "DataObjects/"
["class_prefix"]=>
string(11) "WEBSMS_DBO_"
["ignore_sequence_keys"]=>
string(0) ""
["extends_location"]=>
string(18) "grap_dbo.class.php"
["extends"]=>
string(8) "GRAP_DBO"
["generator_class_rewrite"]=>
string(0) ""
["debug"]=>
int(3)
["debug_force_updates"]=>
string(1) "0"
["production"]=>
string(1) "0"
["table_VoucherLog"]=>
string(6) "websms"
["table_Statistics"]=>
string(6) "websms"
["database_websms"]=>
string(40) "mysql://websms:XXXXXXX@localhost/websms"
}

Expected result:
----------------
I expected it to happily connect ;)

Actual result:
--------------
Through a webbrowser a zero sized result, through command line a segmentation fault (no core dump)

Do you have Zend Optimizer enabled?
Zend Optimizer has some problems with oeverload() AFAIK.

Try to lower your optimization level in php.ini:
zend_optimizer.optimization_level=14

Have you tried upgrading to the latest php version?
You say you are using 4.3.2 on one host and 4.3.3RC3 on the other.
A segfault usually is caused by php itself and not by PEAR but it makes no sense to file a bug for php if you don't use the most recent version.
