Description:
------------
mssql_bind() causes some buffer overruns & memleaks if you try to bind
the same parameter *several times*.
Reproduce code:
---------------
<?php
$c = mssql_connect($host, $user, $passwd);
mssql_select_db($dbase);
$r = mssql_init('nonex_stored_proc'); // that doesn't mean
mssql_bind($r, "param", $param, SQLTEXT, 0, 0, 10);
mssql_bind($r, "param", $param, SQLTEXT, 0, 0, 10);
echo "Done\n";
?>
Expected result:
----------------
Done
Actual result:
--------------
