[fw-general] Undefined variable in Zend_Db_Select

[Luiz Vitor]

The changes in Zend_Db_Select in 1.9.4 release started to raise an undefined
variable notice:


( ! ) Notice: Undefined variable: lastFromCorrelationName in /data/html/
vilagenet.com.br/library/Zend/Db/Select.php on line 828

To reproduce:

$adapter = Zend_Db_Table::getDefaultAdapter();
$select = $adapter->select()
    ->from('sometable', 'id');

$select2 = $adapter->select()
    ->from(null, 'COUNT(*) FROM (' . $select->__toString() . ') AS count');

$result = $adapter->fetchCol($select2);


The variable $lastFromCorrelationName is declared in Zend_Db_Select on line
798, inside an `if` statement, but is used outside it, on line 828.

Moving the declaration to just outside the `if` (line 789) corrects the
problem, and all unit tests still pass.

This is a bug or this is the intended behaviour, and I´m using the component
in a subverted way?

Thanks in advance.
