Description

Given:

default database configuration in LocalConfiguration
separate table mapping in $GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['dbal']['handlerCfg'] and $GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['dbal']['table2handlerKeys'] to an external database for several tables with native type
trying to access Install Tool > Upgrade Wizard throws error "Call to a member function free() on a non-object in typo3\sysext\dbal\Classes\Database\DatabaseConnection.php on line 2748"

Reason:

dbal tries to fetch available database tables from the default connection (typo3/sysext/dbal/Classes/Database/DatabaseConnection.php:2742)
using $this->query() uses $this->lastHandlerKey to resolve the handler instance
$this->lastHandlerKey might not equal the default but any other configured handler configuration, thus the wrong instance is used to resolve the database query

Solution:

initialize $this->lastHandlerKey to the right "_DEFAULT" value
