Bug description: bound params inside of a CONCAT do not work
Description:
------------
Like the summary says... using a bound parameter inside of a CONCAT()
produces strange results.
Reproduce code:
---------------
<?php
$dbh = mysqli_init();
$dbh->real_connect('localhost', 'dbuser', '', 'dbname');
$sh = $dbh->prepare('SELECT CONCAT("xxx", ?, "xxx"), CONCAT("xxx", "abc",
"xxx")');
$sh->bind_param('s', $x);
$sh->bind_result($r, $r2);
$x = 'abc';
$sh->execute();
$sh->fetch();
echo "\n$r\n$r2\n\n";
$dbh->close();
Expected result:
----------------
xxxabcxxx
xxxabcxxx
Actual result:
--------------
On my system, this prints out:
xxxabcxA
xxxabcxxx
The "A" changes on other systems (or goes away). However, both lines
*should* be the same. Change the x's around in the first field and watch
the results get even stranger, or remove them completely to have it work
as expected (except that I need the CONCAT for my query).
