Bug description: PDO_Firebird segfaults when passing lowercased column name to
bindColumn()
Description:
------------
The problem just happens when using lowercased column name in boundColumn
calls. Using uppercased occurs memleaks though. (probably related to
#47414)
Reproduce code:
---------------
<?php
$db = new PDO('firebird:dbname=...', 'sysdba', 'foo');
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING);
@$db->exec('drop table test');
$db->exec('CREATE TABLE test(idx int NOT NULL PRIMARY KEY, txt
VARCHAR(20))');
$db->exec('INSERT INTO test VALUES(0, \'String0\')');
$stmt = $db->prepare('SELECT idx, txt FROM test ORDER by idx');
$idx = $txt = 0;
$stmt->bindColumn('idx', $idx);
$stmt->bindColumn('txt', $txt);
$stmt->execute();
$stmt->fetch(PDO::FETCH_BOUND);
Actual result:
--------------
Program received signal SIGSEGV, Segmentation fault.
