Private report: No CVE-ID:

Description:
------------
The odbc_execute documentation says that...

Elements of this array will be converted to strings by calling this function.

However in what I encountered, more than the array is changed. Variables used to form the param array are changed as well.

Reproduce code:
---------------
<?php
header("content-type: text/plain");
require_once(dirname(__FILE__)."/config.php"); // define connect params
$odbc = odbc_connect(ODBC_DSN, Username, Password);
$b = false;
$b2 = $b;
$params = array($b2);
?>
Before odbc: <?php var_dump($b, $params); ?>
<?php odbc_execute(odbc_prepare($odbc, "SELECT ?"), $params); ?>
After odbc: <?php var_dump($b, $params); ?>


Expected result:
----------------
Before odbc: bool(false)
array(1) {
  [0]=>
  bool(false)
}
After odbc: bool(false)
array(1) {
  [0]=>
  string(0) ""
}


Actual result:
--------------
Before odbc: bool(false)
array(1) {
  [0]=>
  bool(false)
}
After odbc: string(0) ""
array(1) {
  [0]=>
  string(0) ""
}
